Bats are such interesting little creatures. They seem like some sort of bird species gone awry, but they are actually beautifully designed mammals. During early summer walks, we often see one or more bats, fluttering erratically through the sultry air.<br />
<br />
Many bats can navigate and track their food in total darkness using echolocation, the process of emitting inaudible high pitched sonar (10-20 beeps per second) and detecting the returning waves. When the sonar bounces off of nearby objects, the bat adjusts its course accordingly and can close in on a flying insect with perfect precision. Some bats even use their wings to create the sonar. Did you know that the scientists who developed sonar and radar in machines like submarines got their ideas from studying echolocation design in bats?<br />
<br />
There are other animals who live, move and feed in low light conditions who also use echolocation. Animals like whales dolphins, shrews and some birds depend on this specialized design to survive.<br />
<br />
A friend taught us how to have a little fun with our bat friends and see echolocation in action by blowing a quick puff of air in their direction. In so doing, we are sending a wave directing them to quickly change direction or risk crashing into us.<br />
<br />
Watch for bats in the early evenings. Remember that there are only a few species of bats that feed on animal blood (often called Vampire bats) but none of them live in the United States.<br />
<br />
To see bats in Phoenix, visit the Maricopa County flood control tunnel at 40th Street and Camelback Road. The bats use the tunnel as a day roost. Go at sunset to see them exit the tunnel for a night of feeding. Find wonder in the early evening sky.<br />

<br />
Our desert neighborhood is full of bird activity right now. Every morning we wake to a cacophony of sound and see darting motion at every window as birds zip past, frantically carrying out their spring time business. It is not uncommon to see small and mid-sized birds searching the ground for nesting materials and tasty morsels to eat.<br />
<br />
What is uncommon is waking up to see a large hawk perched on our small copper reflection pool, surveying the world with beady, yellow eyes. It's also unusual for any bird to hang around for several hours while so much activity is swirling around it, but that is exactly what happened this morning. After capturing some images and admiring this striking visitor, I grabbed my bird book and began the identification process. Mercifully, it stayed long enough for me to take a good, long look.<br />
<br />
Judging from the hooked beak and powerful build, this bird is obviously a bird of prey. It is actually one of the fastest flying birds in the world, known for its great skill in navigating tree tops at high speeds while chasing other birds. It was my first close up look at a Cooper's Hawk, and in this case, a juvenile with mottled brown streaks and prominent yellow eyes. This species of hawk experiences a change of eye color as they mature, from pale yellow and even grey, to orange and blood red. I am still researching to understand the benefits of eye color changes.<br />
<br />
Cooper's Hawks are not compassionate hunters. They prey on other birds and finish them off by repeatedly squeezing them with their talons. They have also been known to drown their prey by holding them under water until they stop struggling. During nesting season the smaller male is responsible for meal delivery and is perfectly designed for swift flight and tight maneuvering to accomplish the task. His smaller, lighter body coupled with long tail feathers allow this stealthy hunter to glide through an obstacle course of tree limbs with great agility.<br />

</tbody></table>
Like most other birds, Cooper's Hawks have a third eyelid called a Nictitating Membrane. This semi- transparent membrane slides across the eye horizontally or diagonally and not only helps to lubricate the eyes, but provides protection from wind, dust and rain when the hawk is on the wing... amazing design for sure.<br />
<br />
As you track birds this spring, notice the unique design features that make them each successful desert dwellers. If you were a bird of prey, what physical and ability traits would you want to possess?<br />

I love new, interesting words, don't you? When reading about snakes found in Arizona, the word "crepuscular" appeared in the text, which of course triggered my overactive wonder muscle. I had never heard this delightful adjective, used to describe creatures who are active primarily during the most glorious time of day... twilight...gentle, soothing twilight. Not quite nocturnal or diurnal, the animals who prefer this time are unique.<br />
<br />
Twilight is a golden package of fleeting moments, found like book ends on each side of the day. In the morning, it seems to embody the beauty and hope of a new fresh day, and in the evening, it gently wraps the day in a quiet, ethereal light, spilled alongside deep shadows across the landscape. It is a time for seeing and hearing animals in a way unlike any other. Many photographers prefer the soothing, natural light that descends in the hour near twilight, a time when our cameras seem to do their best work.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

One notable crepuscular desert dweller is the Javelina, or Collard Peccary. I have only seen them during twilight hours. Unless sick, javelinas will travel in bands of 6 - 12 animals led by a dominant male. They have many incredible design features, such as their ability to eat prickly pear, spines and all. Javelinas derive most of their water from the plants they eat, so juicy prickly pear are among their favorite. Watch for prickly pear plants that look like they have been torn versus cut or barrel cacti that have been overturned with the flesh scooped about like a tunnel into the underside.<br />
<br />
Javelinas are not considered dangerous if left alone, but an entire band can be aggressive and unpredictable, and if provoked, may attack when there are young or wounded among their members. They also have terrible eyesight, and use their sense of smell to communicate, so you will usually smell the musky scent of a javelina before you see one. They have several scent glands, which are located below each eye and on their back/rump. The glands release a strong odor when marking territory, members of their group, or when they become alarmed or excited.<br />
<br />
The hour leading up to evening twilight is my favorite time to trek in the desert. The harsh mid-day sunlight softens into a warm glow, and as the air cools, a playful breeze carries the sound of owl hoots and cricket songs. Bats and Nighthawks dance overhead, cotton tailed rabbits and other small mammals disappear into the shadows like children heading inside after a long day of play. Although seen other times of the day, Bobcats, <a href="https://desertwondertracker.blogspot.com/2018/02/jack-rabbit-ears.html">Black Tailed Rabbits</a>, as well as some snakes and birds are also considered crepuscular. Many snakes are nocturnal during the hot summer, crepuscular in the spring and fall.<br />
<br />
As you trek at twilight, watch for interesting crepuscular creatures, but remember that it is their feeding time, so try not to disturb them. In the dim light, gaze with wonder at the unique happenings found only at twilight.<br />

Watch your step! Our reptile friends are apparently out in full force. Today, we were out hunting for interesting rocks with our rock-hounding niece Emily and inadvertently came upon a long snake stretched out across our path. Our first reaction was to stop, back away and mentally run through our internal rattlesnake identification checklist. Fortunately, this long, limber snake had a pointy head and tail, as well as round pupils. Here in the west, it is commonly known as a Gopher Snake, but is closely related to and often called a Bull Snake.<br />

Due to their length, coloring and markings, this non-poisonous snake is often mistaken for a Rattlesnake. Gopher Snakes and Rattlesnakes both help keep rodent populations under control and are essential for the health of the desert eco-system. As a desert dweller, it is important to learn the differences between a venomous Rattlesnake and a non-venomous Gopher Snake. One is helpful in your outdoor landscape, and the other is better suited to the open desert.<br />
<br />
<b>Head</b><br />
<b><span style="color: #783f04;">Rattlesnakes</span></b> have triangular heads, with facial heat sensing pits that look like nostrils.<br />
<span style="color: #e69138;"><b>Gopher Snakes</b></span> have narrow, rounded heads, although if threatened, they can flatten their heads to mimic a Rattlesnake.<br />
<div>
<br />
<b>Eye</b><br />
<span style="color: #783f04;"><b>Rattlesnakes</b></span> have vertical, slit pupils, like a cat.<br />
Like most non-venomous snakes in the US, <span style="color: #e69138;"><b>Gopher Snakes</b></span> have rounded pupils</div>
<div>
<br />
<b>Tail</b><br />
<span style="color: #783f04;"><b>Rattlesnakes</b></span> have an ornate cluster of rattles on the tail which grows every time an old skin is shed. . Young rattlers do not have a "rattle" until they shed.<br />
<span style="color: #e69138;"><b>Gopher Snakes</b></span> have a pointy tail, but because they mimic rattlers, it may be hard to see their tail if they are vigorously shaking it.</div>
<div>
<br />
<b>Body</b><br />
<span style="color: #783f04;"><b>Rattlesnakes</b></span> are generally bulkier with a thick middle that tapers on both ends.<br />
<b><span style="color: #e69138;">Gopher Snakes</span></b> can grow much longer than Rattlesnakes, up to 8 feet, whereas Rattlers usually top out at about 4 feet. Gopher snakes are also slimmer and more limber looking than Rattlers.<br />
<br />

<br />
No matter what kind of snake you encounter in your tracking adventures, always leave them alone. Even the non-venomous Gopher Snake can strike with a painful bite. However, most snakes are content to slip away without an encounter and will only bite if provoked or surprised. These amazingly designed creatures are a treat to see in their native habitat if we use caution and give them plenty of space. When we track wonder in the wild, it is up to us to diligently watch where we place our feet and hands. As you move across the trails this spring and summer, remember to track wild wonder with great awe, but also great caution.<br />

Ahhh, nesting season in the Sonoran Desert. From darting Hummingbirds to mysterious Great Horned Owls, the bird world is frantically preparing to welcome the next generation. It is not uncommon to see birds of all types picking at the ground or flying to and fro with a mouthful of building materials. Most birds only build nests for brooding and raising their young, and abandon them once the little ones have learned to fly, although some species build a breeding nest and separate roosting nests.<br />
<br />
Birds are very resourceful when it comes to nest building. Some make elaborate luxury dwellings <br />
complete with roof and welcoming entrance. Others move in to old nests abandoned by others. Still others find refuge in the holes of cactus, trees or even burrows in the ground. Some are notorious nest stealers and others seem to slop their nests together as though the thought of where to put the eggs hadn't occurred to them. Hummingbirds use spider web to weave a tiny sticky nest, then cover it with leaves or lichen. Some birds even go through the extra work of building dummy nests to give the female options or discourage other birds from nesting in the area. The ingenious nest designs of each species suit them perfectly and serve their purpose.<br />

This time of year, take time to watch the birds. What are they doing? Where are they going? Do you see patterns of behavior? Follow a bird's movements and you may discover a nest. Remain at a safe distance or the birds may become spooked and move on. It you notice that they seem to be aware of your presence or abandon their activity, you know you have moved too close. If you find an abandoned nest, study it without touching it as birds are notorious for carrying disease. Try to imagine how a handless bird constructed it.<br />
<br />
No matter where you live, nesting birds are not far. Enjoy tracking them and savoring a unique peek into the most wondrous and mysterious of designs... new, perfectly formed and functioning life!<br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Desert spring is in the air. Bird and insect sounds are louder. Plants are showing off their new tender spring green growth, and each morning, there is definitely a soothing warmth chasing the night chill away. Yet in the desert, there is one tell tale sign that signals the coming of spring more than any other... the appearance of reptiles. These cold-blooded creatures have been hibernating through the cooler months and a series of warm days will cause them to begin to stir. It's their time.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The first reptiles to appear are the small lizards. Due to their size, their body temperature warms and cools more rapidly, so they can warm up and get moving easier than the big guys. This week, we noticed a marked increase in small lizards lounging on the sun-warmed rocks who skitter away at the slightest intrusion.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Hibernation is one of those perplexing design mysteries found in the natural world. Why do some creatures have the ability to slip into an efficient energy saving mode for several months when others have to store food caches, migrate or find some other crafty way to tough it out when food supplies dwindle? </span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">In the case of lizards and other "cold-blooded" or ectothermic* creatures, their bodies are dependent on the outside temperature to regulate internal temperature and fuel their metabolism. Instead of getting most of their energy from the food they eat like mammals do, cold blooded animals are energized by the warmth of the sun. Their muscles are triggered by a chemical reaction that is fast in warm weather and slower in cold weather. Cold blooded, or ectothermic animals are usually elongated or flat in design, allowing heat to be exchanged with the surrounding environment more efficiently. </span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The <a href="https://www.acs.org/content/acs/en/education/resources/highschool/chemmatters/past-issues/archive-2013-2014/animal-survival-in-extreme-temperatures.html">chemical process design</a> in ectothermic animals is fascinating. At the cellular level, water around each cell can freeze, but due to a flow of glucose into the cell, the fluid inside the cell does not freeze, almost like it has been injected with a natural anti-freeze! Animals like frogs can hibernate at temperatures below freezing and still survive. </span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The next time you see a lizard lounging in the sun, remember that this well-designed creature is not interested in sporting a tan, but rather in getting an energy boost! Observe his sleek elongated body which can be quickly warmed through by the heat of the rock underneath and the sun overhead. Brilliant design! </span><br />

This week, we had the pleasure of tracking wonder with British Columbia's wildlife photographer <a href="https://www.facebook.com/A.Bucciphotography/">Anthony Bucci</a>. Anthony has an amazing talent for tracking and photographing North America's owls and was recently in the southwest to enjoy some of our local birds and owls. One owl common to our area is the Western Screech-Owl. True to form, Anthony was able to find this nesting owl and create some amazing photos, giving us a glimpse of the little owl you have probably heard without knowing it.<br />
<br />
Western Screech-Owls are small, about the size of a football. Their feathers are brownish-grey, with lots of variation, which help them blend into their woodland or desert environment. They are nocturnal, coming out to hunt small rodents and insects later in the day and evening.<br />
<br />
Adult Western Screech-Owls nest almost exclusively in tree and cactus cavities. They tend to remain in their nesting area year round, so there is a chance to see them even after the spring nesting season. This owl is quite common in the desert so several owls may be living in the same area, defending small nesting territories, but sharing a broader home territory.<br />
<br />
Get in the habit of glancing at the holes in saguaro cactus plants. The holes usually appear dark, but when you notice a lighter colored or blocked hole, take a closer look. It just might be one of our small owls watching you move past their hangout. Listen for the "bouncing ball" call in which the sounds become closer together like the sound of a ball as it bounces closer and closer to the ground before coming to a stop. Learn to engage all your senses, letting them pick up on the subtleties that will lead you to pure wonder.<br />

As a side note, the Western Screech-Owl looks just like the Whiskered Screech-Owl, except for the color of their beaks. The Western Screech-Owl has a black beak with a tiny bit of ivory on the very tip, whereas the Whiskered Screech-Owl's beak is completely ivory colored. Both can be found in Arizona, although the Whiskered Screech-Owl is not as common.<br />

This trail is a good one for a walking stick or poles to help with stability. Bring plenty of water and snacks. I encourage trekkers to carry a backpack or fanny pack so that hands are free. I have an extra backpack and we can also pack for each other as needed. Hat, sunglasses, sunscreen, camera, etc.</span><br />

There are places to stop and catch your breath while taking in the view. Switchbacks continue on to a section where the trail is fairly level before starting a second series of switchbacks. We will keep a steady pace to reach the monolith (Tom's Thumb) where we can rest and look for Prairie Falcons or Swifts who nest on the area's lofty cliffs and crevices. </span><br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br />This morning was cool and windy. I took off before sunrise to see if I could spot any interesting creatures starting their day or finishing their night hunts. As the sun began to spread its light and warmth across the landscape, all was still except for the early morning bird calls. As I turned to start for home, a Black Tailed Jack Rabbit burst from behind a boulder and bounded off through the brush.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">In our area, we see oodles of cotton tailed rabbits, but spotting the large muscular hare known as a Jack Rabbit is a little more unusual. Jack rabbits are actually not rabbits, but hares, and the two are completely different species. Jack Rabbits are fun to observe. Jacks can jump up to 10 feet and run at 40 miles per hour! It is comical to see them bouncing over the landscape like a Loony Tunes character.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Jack rabbits do tend to hang out in large open areas. I have noticed that if I see one in an area, there are probably more and the abundance of rabbit droppings seems to confirm my theory. There are five species of jack rabbit found in the desert. Two of the most common are the Black Tailed and the Antelope. Antelope Jacks are slightly larger and have ears edged in white, whereas the Black Tailed Jack has ears tipped in black as well as black on the tail, hence the name.</span><br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Jacks are known for their huge ears, which not only give them excellent hearing, but serve to help </span><span style="font-family: "helvetica neue", arial, helvetica, sans-serif;">cool the jack by releasing heat from the large surface. The skin on their ears is very thin and full of blood vessels. During the hot part of the day, a jack rabbit will retreat to the shade where the slightly cooler air will cause blood vessels in their ears to widen, allowing more blood to flow to their ears. Some of the resulting heat in the ears will move into the cooler air, ultimately cooling the hot rabbit too. Interestingly, rabbits don't pant and sweat as much as some other animals do, which helps to preserve precious internal fluid. The jack rabbit's cooling system design is perfect for a desert dweller.</span><br />

The Sonoran Desert is enjoying a cool spell, providing gorgeous weather for an afternoon trek in the <a href="http://www.mcdowellsonoran.org/">McDowell Sonoran Preserve</a>. Three of us met up to trek out to Balanced Rock and marvel at the towering saguaros on the way. On our return, we stopped to enjoy the noisy chatter of two ground squirrels, when a sharp-eyed trekker spotted large mammal movement below the trail.<br />
<br />
At first, we thought it was a juvenile coyote, but there was something different about it... more delicate and angular, with enormous ears. Turns out it was a beautiful little gray fox.<br />
<br />
Foxes are nocturnal, so it is not easy to see them. However, the gray fox also can be seen out and about during the morning and early evening hours searching for a wide variety of things to eat from small mammals and reptiles to berries, beans and cactus fruit.<br />
<br />
Gray foxes are known for their unique ability to climb trees using their sharp, thick and slightly curved claws. Their tree climbing ability enables them to escape many predators such as coyotes and dogs trailing them.<br />
<br />
The untouched boulder-strewn terrain found of the area is the perfect place for a gray fox pair to create a den for their young, usually born in the spring. On this particular day, this gray fox seemed to be enjoying the cool, sunny afternoon as he ignored the scolding squirrels. After a couple of minutes, he turned on his paws and trotted off, quickly camouflaged against the backdrop of granite and creosote. Wonder in the desert is often fleeting, so enjoy the moment.<br />
<br />
<b>Points to Ponder for Young Trackers</b><br />
<ul>
<li>When you trek in wild places, pay attention to the birds and animals. Sometimes a flitting bird or chattering squirrel is a warning. Stop and survey the terrain to see if you can spot a potential predator.</li>
<li>Learn about <a href="http://www.naturetracking.com/">animal tracks</a>. It is sometimes hard to see tracks in the dry dusty soil of the desert. Check areas where water collects. </li>
<li>Scat, fur and other animal remains can give us clues about what animals frequent the area. </li>
<li>Look for areas with steady food and water sources. Berries, nuts, seeds and lush foliage attract insects, birds and smaller animals, and where there is an abundance of prey, larger predators are sure to appear.</li>
<li>Always, track with caution. Wild animals are fun to see, but need to be enjoyed at a safe distance. Animals who are sick, accompanying young or and/feel threatened can be dangerous.</li>
</ul>

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">During a recent Desert Wonder Tracker Meetup, we had the pleasure of walking in the midst of giants... giant boulders that is. Geological processes have graced our area with an abundance of enormous boulders and precariously balanced rocks (PBRs), creating the illusion of being on another planet or an episode of the <i>Flintstones</i>. When trekking through such an area, the puzzled expression associated with wonder always begins to ripple across faces and one burning question invariably comes up.. how did these boulders get here? </span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">To begin to understand the how, first study the composition of the boulders. They are all granite, which is igneous rock crystallized from molten magma below the surface of the earth. Granite has both large and small crystals made of light colored elements and minerals, mostly quartz and feldspar, with some mica and other minerals tucked here and there. </span><span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The design of earth's rock cycle is quite elaborate as we scratch it's dusty crust to see the wonders below.</span><br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Granite boulders such as we see in north Scottsdale are the result of a two stage process. These giants once rested underground in a subsurface that trickled with chemically active water that seeped into joints and fractures, causing weathering and breakdown of rock along those weaker surfaces. Over time, the remaining stronger rocks became sphere-shaped core stones beneath the land's surface. Spheres are the only shape that has no single weakest point and no single strongest point, and in the case of these boulders, the more vulnerable edges and points have eroded away.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The second stage began when water, wind and gravity stripped the loose rock material away, leaving the spherical core stones in place. Some of those core stones happened to be resting on stones beneath them, and because our area experiences very little seismic activity, remain standing today. Scientists are still working to understand how factors such as slope, bedrock properties, spacing of joints, as well as weather, impact these amazing natural sculptures. </span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Across Arizona, there are several sites with terrain similar to north Scottsdale. </span><a href="https://www.visitarizona.com/uniquely-az/parks-and-monuments/granite-dells-at-watson-lake" style="font-family: "helvetica neue", arial, helvetica, sans-serif;">Granite Dells in Prescott</a><span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">, </span><a href="https://www.visitarizona.com/uniquely-az/parks-and-monuments/chiricahua-national-monument" style="font-family: "helvetica neue", arial, helvetica, sans-serif;">Chiricahua National Monument</a><span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"> in southeast Arizona are two excellent examples. Rock fields seen along state route 87 between Phoenix and Payson or along Interstate 10 between Benson and Wilcox also offer good views of precariously balanced rocks. </span></span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">When you go, be sure to take a magnifying glass to study the composition of granite. Take time to imagine huge boulders buried underground before they gradually made their appearance as you see them today. Look for fractures and weak </span><span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">places on the boulders where erosion will continue to shape each one. See how many different sizes of granite boulders, rocks and stones you can find. Most importantly, let wonder take you away.</span></span><br />

<b><span style="color: #b45f06; font-size: large;">Calling all Curious Desert Wonder Trackers!</span></b><br />
<b><br /></b>
<b><span style="color: #b45f06; font-size: large;">What:</span></b> Trek to Balanced Rock through a beautiful area of huge boulders and healthy saguaro cactus stands over a well-maintained trail. This trail makes a gentle elevation climb of 200-300 feet. We will stop as needed along the way with Sharon leading and Paul following to allow each trekker to set his/her own pace. The trail is 4.5 miles round trip.<br />
<br />
<b><span style="color: #b45f06; font-size: large;">When</span></b>: Thursday, February 22 -1:30 p.m. to Sunset?<br />
AND/OR Thursday, March 1 -1:30 p.m. to Sunset<br />
<br />
<b><span style="color: #b45f06; font-size: large;">Where:</span></b> Balanced Rock via Granite Mountain Trailhead<br />
<u>Directions</u>: East on Dynamite to 136th Street. Turn left onto 136th and travel north to the parking lot for Granite Mountain Trailhead. The lot aligns with Lone Mountain Rd, is marked by a brown sign and is located right under the power lines seen from 136th Street. Turn left into the parking lot.<br />
<br />
<b><span style="color: #b45f06; font-size: large;">What to Bring:</span></b> We will be traveling over some rocks and loose soil, so good shoes with good tread are a must. Most of the trail is fairly level, but if having a walking stick or poles helps you, bring them. Bring plenty of water and snacks. I encourage trekkers to carry a backpack or fanny pack so that hands are free. I have an extra backpack and we can also pack for each other as needed. Hat, sunglasses, sunscreen, camera, etc.<br />
<span style="color: #b45f06;"><br /></span>
<span style="color: #b45f06; font-size: large;"><b>What to Expect</b>:</span> We will hike out to balanced rock and talk a little about the incredible boulder formations in our area. Since there are so many saguaros along the way, we can talk about them as well. Hopefully, the recent rain may have encouraged some of the wildflowers to pop. Plan to rest awhile at balanced rock, eat, photos, etc. then we'll start back in the golden light of late afternoon. Gorgeous!<br />
<br />
So that we know to wait for you, please let me know if you plan to join us for either trek. See you on the trail! speganydesign@gmail.com<br />

<br />
It all began with an afternoon walk in the desert. For some reason, I kept noticing animal poop. Rabbit poop, coyote poop, bird poop and even insect poop. All different in shape, size, color and even content. As much as I tried to resist it, I could feel the unmistakable stream of wonder begin to trickle through my mind. Sometimes, controlling wonder is a tricky proposition.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrOewKeNqwHX4EnCbYujZFETyS6GXT6VgbgQ65ZIM9GQxZBdLxeQ235DIBQQQ74stVS-2PAUDfZBym51K-tf-zrCxGbnuWxoasRcphw6SZGNIMRD8b6OiYUaAkwS8OBdOS41TyfFbZI4w/s1600/IMG_5697.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="1600" data-original-width="1067" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrOewKeNqwHX4EnCbYujZFETyS6GXT6VgbgQ65ZIM9GQxZBdLxeQ235DIBQQQ74stVS-2PAUDfZBym51K-tf-zrCxGbnuWxoasRcphw6SZGNIMRD8b6OiYUaAkwS8OBdOS41TyfFbZI4w/s200/IMG_5697.jpg" width="133" /></a>As I trekked through an area with lots of wild rabbits, I noticed two kinds of droppings, one light and one dark. It seems that rabbits do indeed excrete two varieties of droppings. The lighter colored one is simply waste, but the darker dropping is actually a nutrition-packed pellet that rabbits eat to remain healthy. In fact, both wild and domesticated rabbits deprived of them will suffer from malnutrition.<br />
<br />
Many of the granite boulders in the area have the white-stained streaks of bird droppings, triggering another wonder response... why is bird poop typically white and not dark like most animals? Birds do not urinate. Instead, their bodies go through a similar process of gathering waste, but when it comes time to get rid of it, the waste is released from just one place instead of two. This all-purpose passageway is also where eggs exit the bird's body. Like mammals, bird's kidneys filter blood to extract waste. Since birds do not urinate, the extracted uric acid waste combines with solid waste, dissolving much of the solid mass and turning it white. The final "product" is one white blob with specks of darker solids here and there. This no frills design may help birds retain water, as well as keep their bodies lighter for flight.<br />
<br />
The orb web spider, Cyclosa Ginnaga actually builds a spot in their web that resembles a splat of bird poop. The spider itself sits in the center to add to the illusion. This ingenious trick helps protect the spider from would-be predators, such as wasps, who are not much interested in a bird poop lunch.<br />
<br />
Animal scat or droppings are not fun to look at, but if you can get passed the gross-out factor, scat can tell us a story about who is in the area, how healthy they are and what they are eating, among other things. Trackers look for bird droppings on rocks and cliffs to find perches and nesting sites. Small mammal scat can tell us about predator/prey relationships. Large mammal scat from bear and cougar can serve as a warning.<br />
<br />
When you are trekking and tracking wonder, be aware of animal scat and see if you can "read" the tales it tells. Help children develop a healthy curiosity about all aspects of nature. Learning to understand every process, no matter how unpleasant it may be, is just part of cultivating wonder and discovering design.<br />
<br />
<b><u>Questions for Young Trackers:</u></b><br />
<ul>
<li>Who does this scat belong to? Bird, Mammal, Retile, Insect? How can you tell?</li>
<li>Did the scat come from an herbivore, carnivore or omnivore? How do you know?</li>
<li>Do you see evidence of bird perches in the area?</li>
<li>How many different kinds of scat can you find?</li>
<li>What can you learn about an animal by studying its droppings?</li>
</ul>

<br />
Stop what you are doing and go outside. Close your eyes and concentrate on listening to individual sounds. My guess is that you will hear at least one bird voice in the cacophony of sound. Birds are a part of our everyday auditory experience. The world would be a strangely quiet place without their calls, chirps, whistles and screeches.<br />
<br />
Birds amaze us and delight us, but did you know that they play a significant role in understanding ecosystems and environmental health? Birds are critical to the process of pollination, as well as insect and rodent control. Scientists have learned about environmental dangers by observing the changes in bird populations. For instance, declining populations of bald eagles and peregrine falcons revealed the problem of DDT and heavy metals in the environment. Coal miners once carried small cages containing canaries to detect the presence of carbon monoxide and other gases.<br />
<br />
If you or your child/grandchild have an interest in birds, you may consider starting a free account with <a href="http://ebird.org/">ebird.org</a>. This amazing site/app enables bird trackers world-wide to create sighting lists as well as upload images and sound recordings into a personal account. The information you provide becomes a part of an enormous database of information that helps scientists and other birders track birds and understand their impact. It is easy and fun to have a place to record your own experiences while also watching your data become a part of something so useful to others.<br />
<br />
Using eBird also builds many important life skills. Information provided by bird trackers merges to create interesting charts and maps that can be studied and analyzed to answer your questions. Challenge children to organize a bird tracking expedition by identifying species, where they are in each season and how to navigate to each location. Critical reading comprehension, data analysis, map and navigational aptitude are just a few of the skills used to plan a trip. Observation, photography, data collection and report writing are skills used to gather and upload information to the site.<br />
<br />
Bird tracking can become a life-long passion and enjoyed no matter where life takes us. Tracking birds often leads to other interests and connects us with a vast community of people all over the globe. If nothing else, it triggers a delicious sense of wonder on a daily basis and keeps us gazing heavenward.<br />

It's almost spring here in the southern deserts... earlier sunrises, later sunsets, and a slight warmth wafting through the air are all signs of a change. Another unmistakable mark of spring is the boisterous sound that fill the mornings. Birds, seen or unseen, become very chatty and seem to be trying out new songs for a new mating season.<br />
<br />
Bird watching has long been associated with groups of senior citizens tip-toeing through marshes and woodlands, but the practice can be a natural skill builder for both adults and children, especially when they are exposed to it early. Consider just some of the benefits of bird tracking.<br />
<br />
<b><i>Birds can be found everywhere, from open farmland to crowded inner cities</i>.</b> Their ability to thrive in such diverse settings is in itself an incredible design feat. From a messy nest high in a sprawling tree to a lone metal perch outside an urban high rise window, birds are present near all our homes. The natural world can sometimes seem stagnant and slow to change, but birds offer us a constantly shifting view of life in the animal world.<br />
<i><br /></i>
<i><b>There are so many different kinds of birds</b></i>. <a href="https://www.amnh.org/explore/news-blogs/research-posts/study-doubles-estimate-of-world-bird-species">The American Museum of Natural History</a> estimate there to be as many as 18,000 species of birds worldwide. Learning to identify size, shape, plumage designs, calls, movement, behavior, nest building habits and migration patterns offer endless ways to hone precise observation skills. Wild birds must be quickly analyzed from a distance before they vanish from sight and earshot. Children can be taught to pay attention to main features, as well as subtle details as they sharpen their observation skills.<br />
<b><i><br /></i>
<i>Bird tracking builds vocabulary</i></b>. Think of all the comparative adjectives even young children can learn in the process of describing their feathered friends. Is it large or small, slender or compact, spotted, striped, plain or mottled? What are their beaks and tails like? Is their flight smooth or choppy?<br />
<b><i><br /></i>
<i>Tracking birds teaches us about design</i></b>. Books and online resources can help children understand the unique design of birds; light-weight bones, feather and beak design according to function, hunting and defensive behaviors. There is no end to the weird and wonderful design features found in the world of birds.<br />
<i><br /></i>
<i><b>People learn from birds</b></i>. Why did it take people so long to figure out how to copy flight? What design features did people duplicate in order to create flying machines? We are still learning about the navigational skills of birds. How can some fly for hours without stopping over thousands of miles to land at a specific destination?<br />
<br />
<i><b>Birds are generally harmless to humans</b></i>. We can enjoy these feathered wonders without fear of being attacked, gored, bit or sprayed. Some birds will warn us to back off with loud calls or gutsy swoops, but for the vast majority, birds would rather take to the air than interact with humans. Do practice caution when handling anything that belongs to a wild bird due to the parasites, bacteria and viruses that can be carried.<br />
<br />
Can you think of more benefits to bird tracking? This week try to be aware of the birds around you. Turn off artificial sound makers and tune into the sounds of birds. Scan your surroundings for bird activity. This time of year, you will catch birds collecting nesting material or acting strangely as they carry out their mating rituals. Some will delight you with what looks like joy. The joy of riding the breeze as only a bird can.<br />
<br />
Happy Valentine's Day!<br />

The Valley of the Sun is home to many interesting rock formations forged long ago by heat, cold, water, pressure, wind and weathering. One unique area is on the east side of the McDowell Mountains where you can climb into the middle of an ancient landslide known as the Marcus Landslide, which also happens to be the second largest landslide in Arizona.<br />
<br />
Boulders the size of a small house dot the landscape, haphazardly situated in the path of the slide. Tracing the jumble of boulders up the slope, it is easy to spot the concave basin where the rocks originally broke away from the mountain. The break away scar begins almost at the top of the mountain, where rocks and debris broke off and fell down a steep 300 foot fall zone. The momentum, coupled with the finer matrix material beneath, allowed the boulders to slide an additional 4,000 feet to the east.<br />
<br />
One of the most notable boulders in the area is "submarine rock," aptly named by those who originally studied the landslide. Erosion has hollowed out a little open grotto at the base of the rock, accessible by a short trail and a great place to stop for lunch or a snack. Many of the boulders in this particular area are cylindrical in shape and are lying in an east-west direction. Scientists still do not understand how the boulders lined up during the slide.<br />
<br />
The <a href="http://www.mcdowellsonoran.org/hike/marcus-landslide/">Marcus Landslide trail</a> starts at the <a href="http://www.mcdowellsonoran.org/trailhead/toms-thumb/">Tom's Thumb Trailhead</a> in the McDowell Sonoran Preserve in Scottsdale. It is a relatively flat trail, sloping southeast past a magnificent stand of chain fruit cholla and many interpretive signs about the interesting geology of the area. At about 1.5 miles, a .7 mile loop trail climbs into the heart of the landslide. Be sure to take plenty of time to complete the 4 mile roundtrip trek and take lots of water as there is no water at the trailhead. As always, good shoes with good traction are a must.<br />
<br />
Exploring this area will trigger a land slide of wonder and questions about geologic processes.<br />

August, 2017 saw a total eclipse of the sun. Although not quite as show-stopping, 2018 has some gems in its line up too. To kick off a new year of wonder and design tracking, be sure not to miss the total lunar eclipse in the early hours of Wednesday, January 31. It is also a super moon and a blue moon. It is easy to watch, requires no special eye protection, and has an off the charts wow factor.<br />
<br />
There are at least two lunar eclipses each year. This heavenly wonder event occurs when the moon's orbit takes it into the earth's shadow. As the moon slips into the earth's shadow, it takes on a reddish hue, giving it the creepy moniker of "blood moon." Due to predictable order and patterns in space, we know that two or three eclipses tend to occur within a short period of time. A solar eclipse always happens two weeks before or after a lunar eclipse.<br />
<br />
The only problem with the January 31 eclipse is that it begins in the Phoenix area at 3:51 a.m., so you will have to pry your warm bones out of bed to see it the earth's shadow begin to sweep across the moon. However, complete coverage will occur at 6:29 a.m. so take your breakfast outside and start your day with a magnificent wonder. Look to the north/northwest low on the horizon. If you do not live in Phoenix, check the <a href="https://www.timeanddate.com/eclipse/lunar/2018-january-31">eclipse map</a> to see if the eclipse will be visible in your area. As expected and right on schedule, also watch for the partial solar eclipse on February 15, 2018.<br />

If you are brave enough to venture back into Arizona's wild and shady history, go no further than Vulture City, about 12 miles outside of Wickenburg. The Vulture mine and surrounding property has changed hands a couple of times and is currently being renovated in hopes of restoring it to within squinting distance of its original state.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiHCBLPstn0nHSF8ONOoV5OQwaQ5J9Q4NVujNsl-DMAhLMoaYiThfzFy7hRFidPojLnG9tKubLPnTgRJPSexv42tOiJUKweBzV1BD0fTQV7Vkzk6F8hlK-t6bbMW7PuFPQwp_oGeoqESms/s1600/IMG_5513.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="1600" data-original-width="1067" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiHCBLPstn0nHSF8ONOoV5OQwaQ5J9Q4NVujNsl-DMAhLMoaYiThfzFy7hRFidPojLnG9tKubLPnTgRJPSexv42tOiJUKweBzV1BD0fTQV7Vkzk6F8hlK-t6bbMW7PuFPQwp_oGeoqESms/s320/IMG_5513.jpg" width="213" /></a>The place is an eclectic museum of gold mining in the mid 1800s with buildings and original artifacts telling the story of desperate men clamoring after the southwest's king of rocks - cold, hard, glittering gold. Visitors see remnants of the actual tools and machinery used to collect and process gold. They can also sense the danger surrounding gold operations of that time as they behold the "hanging tree," which quickly dealt with those who attempted to steal the bright treasure.<br />
<br />
It is believed that there is a lot of gold in the core of the earth. Over time, with seismic activity and the movement of molten liquids, it has been pushed to the surface of the earth's crust. Along with other minerals like sulfer, it flowed into underground cracks and cavities, forming veins of ore as it cooled. Natural processes of erosion carry specks or nuggets of gold into streams and rivers, and because it is one of the heaviest minerals, gold sinks to the bottom when panned.<br />
<br />
Arizona has some of the most widespread gold deposits of any state in the US, as gold has been found in almost every county. Small prospecting ventures have been popular here with supposedly lots of gold yet to find. Even today, there is an active group of gold prospectors and pan handlers who track gold, particularly in washes, where gold flakes tend to appear.<br />
<br />

Finding real gold takes effort, but other rocks that sparkle and shimmer are also fun to find, from mica to pyrite to hematite. Sparkling flakes of mica are common in rocks found in the desert. Pyrite is also called "fool's gold" due to its resemblance to the real thing. It is inexpensive and a must for any rock collection. Tracking interesting rocks and minerals often leads to learning about historical figures who also tracked wonders of our earth's crust.No matter where you live, the earth provides beautiful treasures underfoot, so be sure to take time to look down as you track wonder.<br />

On the road out to Vulture City, there is a wonderful hike up to Vulture Peak. Watch for signs directing travelers into a parking lot. It is rated as moderate, but does become more strenuous at the top. Be prepared to do some rock climbing to reach the very top. Not recommended for very young trackers.<br />

You've probably heard of nature preserves, mountain preserves and animal preserves, but did you know there are rock preserves? Preserved rocks are not your average rock specimens, but rather special stones etched with images known as petroglyphs that once served as canvases for expressing and preserving ideas. Due to the enduring properties of rock, these ancient works of art can still be found in arid regions all over the world, but can be easily missed if you haven't got your best tracking eyes wide open.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
</div>
At first glance, petroglyphs appear to be rock paintings with a lighter medium brushed over a dark substrate. In reality, light rock is hidden under a dark outer layer known as desert varnish. The dark varnish is a combination of clay, dust, and other minerals cemented to the rock by bacteria as it slowly builds up on the lighter surface of volcanic and sedimentary rocks. Desert varnish can be black, brown or reddish, depending on mineral content. Interestingly, scientists still do not understand exactly how it forms.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjcIHgjpBNMgD8CX7n28h9aTvG329tWy-2JkuDvdZSzKy-fkeslE74Z4BjzVGLq7dBrKbm4dosEoV14UievtR3w6osCQ4334MYafI1phKxEFiSkw58DOV60QycWTC4Q9y0lyG3CXO5ChL4/s1600/IMG_5390.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1067" data-original-width="1600" height="213" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjcIHgjpBNMgD8CX7n28h9aTvG329tWy-2JkuDvdZSzKy-fkeslE74Z4BjzVGLq7dBrKbm4dosEoV14UievtR3w6osCQ4334MYafI1phKxEFiSkw58DOV60QycWTC4Q9y0lyG3CXO5ChL4/s1600/IMG_5390.jpg" width="320" /></a><br />
Ancient people pecked, scraped and pounded pictures into the hard surface, revealing the lighter colored rock just below the varnish. After surviving thousands of years of weathering, we still have this cryptic symbol language dotting caves, hillsides and shorelines. They are truly treasures and cause us to wonder about the role of rocks in the past.<br />
<br />
In the Phoenix area, one collection of over 1,500 petroglyphs can still be viewed undisturbed on the rocky hillside just south of the Adobe Dam at the <a href="https://shesc.asu.edu/dvpp">Deer Valley Petroglyph Preserve</a>. Visitors learn about the history of the area and the people who spent time there over the centuries, then proceed to the actual rock strewn hillside where dramatic images appear to glow from the jumble of huge basalt boulders. When you go, plan enough time to stand before the rocks from different angles and let your eyes adjust to the ancient language before you.<br />

<br />
The southwest deserts are notorious for dramatic rock sculptures and it does not take trekkers long to wonder how such wild formations were formed. As it turns out, heat, water and wind have done their work over time, and continue to weather and shape the land today.<br />
<br />
When most of us think of volcanoes, we imagine exotic places like Hawaii or the doomed ancient city of Pompeii. Rarely do we associate volcanic activity with the deserts, but much of Arizona was forged by volcanic activity. Rising from the eastern edge of the Valley of the Sun stand the majestic rocky wonders known as Four Peaks Wilderness and the Superstition Mountains.<br />
<br />
The Superstition Mountains are the remains of a volcanic caldera*, which is a bowl-like formation caused by a major collapse at the very heart of the molten volcano. As the volcano emptied its contents outward, it created a huge underground cavity. As the weight above the cavity increased, it eventually collapsed back into the hollow cavity. The cooled remnant is what we see today.<br />
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgI_5epCqc2ja7yc6WvXAgswk1EJIMXh1g_EKuqEXfeLk9G1m5RqnTu3GZgsXziIrZ5bxEz-kSz_4UTQFMx6U8AIiybhqOCJmrDMJ15GayzyGqlUI1nePPGbghjcFKXRZDhaDIhB4AQfPo/s1600/IMG_5141.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="1600" data-original-width="1067" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgI_5epCqc2ja7yc6WvXAgswk1EJIMXh1g_EKuqEXfeLk9G1m5RqnTu3GZgsXziIrZ5bxEz-kSz_4UTQFMx6U8AIiybhqOCJmrDMJ15GayzyGqlUI1nePPGbghjcFKXRZDhaDIhB4AQfPo/s400/IMG_5141.jpg" width="266" /></a>Tracking wonder in the Superstitions is an awe-inspiring workout. To think that you are climbing among the treasures of an old sunken "ship" is wondrous enough, but the unusual, time-weathered rocks provide instant objects of curiosity and wonder. Hoodoos and PBRs (precariously balanced rocks) line the canyons. How did they come to rest where they are, stacked up like a child's blocks just begging to be toppled?<br />
<br />
There are many trails in the Superstitions. The Siphon Draw Trail is a popular, yet challenging trek. The trail is rocky and rugged, so wear sturdy hiking boots with good traction. Cross the relatively flat area leading up to the mountain and into the draw. If you are able, climb as far as the smooth rock basin where water flows off the steep walls during rain. It makes a good destination for a picnic and provides good views of the rocky wonders above. Climbing beyond the basin is very strenuous and tricky, not recommended for inexperienced hikers. While there, fire up your imagination with tales of the ancient geological and historical secrets contained in the steep walls. Descending in the light of a setting sun is magical, a wonder long remembered.<br />
<b><br /></b>
<b>* </b>In geographic terms, a caldera is a formation in which the outline of the volcanic collapse is presently visible. Cauldron is the term given to a caldera whose borders are no longer seen. Crater Lake in Oregon is actually a good example of a well defined caldera.<br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Say what you will about our dry, brown landscape, but no one can deny that where the Arizona desert falls short in lush foliage, we excel in rocks and minerals. This is rock hound country. I have been studying rocks since I was a wee little one, digging in the driveway gravel. The desert is a treasure trove for people like me. I can't say that I have found anything valuable, but I have picked up thousands of rocks in my life, turning them over in my hand, wondering and wondering some more.</span><br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Arizona is one region where the earth bares her bones - we can easily see the design that gives the land structure, plants a medium for running down roots and raw material with which we build and create. It is home to the famous Grand Canyon and numerous mining towns. Here, we easily see caverns, meteor craters and ancient landslides, massive boulders stacked up like a child's blocks and bright flashes of mineral glitter in common piles of dirt.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Clear and colored crystals formed by heat and pressure never cease to amaze us. Some are so stunning that even a master jeweler could not compete with their wild beauty. Geodes are spherical rocks that contain a hollow cavity. What makes them such treasures to rock hounds is that crystal formations are often found inside, but only after the rather homely looking "rock" is cracked or sawed open. They are formed in various ways, but at some point, minerals dissolved by the heat of a volcano or the water in sedimentary layers became trapped as an outer layer of rock cooled around them.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Most children are fascinated by interesting rocks and showy crystals. This is the time of year to take advantage of all the rock hound events around the state or just examine common rocks found close to home. The cooler temperatures are more conducive to searching landscapes for special rock and mineral treasures. One of the most noteworthy destinations is the huge meet in <a href="https://www.desertusa.com/cities/az/quartzsite.html">Quartzsite</a>. About 3,000 rock, mineral and gem vendors from all over descend on the little town during the first two months of the year. All shows are free and the prices are notoriously cheap, especially when compared to other shows in the state. It is a true rock hounder's paradise. Children as well as adults marvel as the magnificent wonders found in the earth's dirty crust. </span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">Start the new year with a good strong dose of rock-hard wonder! </span><br />

<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">2018 began with a big, bright moon floating in a clear desert sky. We regularly enjoy a soothing bath of moon glow over our open landscape, but every so often the moon appears larger and brighter, which is yet another reason to get outside and let the delicious sense of wonder kick in. On bright Supermoon nights, we like to walk out into the open desert, as far away from artificial light as possible. The desert landscape takes on a cool, ethereal glow. Sharp edges soften, hues darken, surface minerals shimmer, and the soft sounds of nature are more distinct. </span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">So what is the allure of a Supermoon or Super Full Moon? For starters the moon's orbit path is elliptical rather than circular, causing its distance from earth to vary as it makes its 30 day trek around our blue planet. During those times, full moons can appear 14% larger and a whopping 16% brighter than the average full moon. Supermoons are also somewhat rare. Although the term Supermoon is not an official astronomical term, it is an easily remembered one for an event that only happens 4-6 times a year and some of those Supermoons are new moons so they are not visible.</span><br />
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "helvetica neue" , "arial" , "helvetica" , sans-serif;">The most dramatic time to view a full moon is at <a href="https://www.timeanddate.com/moon/usa/phoenix">moon rise</a>. As the moon peeks over the horizon, it appears even larger due to an optical illusion. When this giant heavenly body is seen beside earthbound features such as mountains or buildings it looks larger in comparison. It is interesting to note that the moon rises about an hour later each night and into the morning. Challenge your family to a moon tracking contest and see who can spot the moon first each night. Try to guess where it will rise. Look for patterns. Paint or draw the moon phases. Study the surface of the moon through a telescope or binoculars. </span><br />
