As with its neighbor, Canyonlands National Park, Arches National Park conceals most of its wildlife from visitors. That said, lizards are easy to spot, as are mule deer in the cool times of the day. And if you spend a little time before breakfast, or after dinner, you just might see coyotes, porcupines, desert cottontails, black-tailed jackrabbits, and many songbirds.

Because of the high heat during the summer months, most of these animals will be most visible when humans are not typically out and about. Desert animals have a variety of adaptations to deal with the hot weather and aridity. A key adaptation is that most animals are nocturnal, being most active at night. Nocturnal animals in Arches include kangaroo rats, woodrats (also called packrats), and other small desert rodents, skunks, ringtails, foxes, bobcats, mountain lions, bats and owls.

Some desert animals are “diurnal”, or primarily active during the day. These include rock squirrels, antelope squirrels, chipmunks, lizards, snakes, hawks, and eagles.

Many animals have are only active in certain temperature ranges, and they alter their active times of day depending upon the season. During winter months, snakes and lizards are in an inactive state of “torpor,” or sluggishness or even dormancy. But they become active during the day during the late spring and early fall, and then become “crepuscular,” or active mainly during the nighttime hours, to avoid the daytime heat of summer.

Insects, too, alter their times of activity. Mosquitoes, as you no doubt know, may be out from dawn through dusk, depending on the temperatures. But they are not active after the sun goes down.

In spite of Arches’ rather inhospitable appearance, almost 50 species of mammals live in the park’s landscape. But the hot climate and lack of water favors small mammals. Because of their size, these animals are less able to migrate, but have an easier time finding shelter, and require less food and water to live. Rodents are numerous: there are eleven species of mice and rats.

Desert bighorn sheep are one of the larger mammal species to be seen. They are frequently spotted along Highway 191 south of the park visitor center, and call Arches home all year long. They roam the talus slopes and side canyons near the Colorado River, forage for plants, and negotiate the steep, rocky terrain with the greatest of ease.

While Arches may not be considered a prime bird watching hot spot, 273 species have been seen in the park, which includes seasonal, year-round residents, and migrants.

Much of this diversity is due to the riparian corridors like Courthouse Wash and the Colorado River (which forms the park’s southern boundary). Mornings along these corridors often are filled with birdsongs during spring and summer. You might spot blue grosbeaks, yellow-breasted chats, and spotted towhees. Listen carefully and you’ll hear the trill of the canyon wren echoing from the sandstone walls. Great blue herons hunt the shallows for fish, while Cooper’s hawks deftly maneuver through the tangle of trees beyond the riverbanks.

There is life in the desert, if you know where, and more importantly, when, to look for it.

Hi, I’m Ru Mahoney with Stokes Nature Center.

If you’ve ever had the opportunity to visit Stokes Nature Center in the Uinta-Wasatch-Cache National Forest, you know that we’re located about a third of a mile up a narrow trail cut out of a steep slope of the Bear River Mountains on one side and dropping down into the rocky waters of the Logan River on the other. Which is why it’s always a particularly sobering experience, when making a winter morning trek up the aptly named River Trail to the nature center to find my way blocked by 1200 pounds of antlered bullish brown bulk, standing 6 feet at the shoulder. In case you’ve never happened upon a moose yourself, they are what happens when Mother Nature decides that the bulk of an NFL player and the legs of a supermodel should get together in one massively large and absurdly leggy Deer-zilla. And while I’ve never met a moose who’s bored browsing and indifferent glance didn’t make it pointedly, and yes, a little painfully obvious that I was far more impressed with them than they’ve ever been with me, they can pose a threat to the incautious admirer. While I don’t encounter moose every month of the winter, I do hear well-intentioned nature center visitors talk frequently about their own encounters, which too often include accounts of trying to get closer to snap a great picture.

Moose are the largest member of the deer family in North America, and are found in the north and northeastern forests of Utah. Despite their size and top heavy appearance, they thrive in watery environments. An adult moose doesn’t hesitate to wade into deep water to browse on aquatic vegetation and can often be spotted swimming effortlessly across lakes and marshes to get to prime grazing or escape a perceived threat. Their hollow hair makes them incredibly buoyant swimmers and keeps them well insulated against the cold both in and out of the water. In winter months they may leave frozen high alpine lakes and seek out forage on evergreens and bark, making encounters on lower elevation hiking trails more likely.

Male moose rut in the fall, tirelessly seeking out willing females. Easily distinguished by their large antlers, which can spread to more than 4 feet across, a bull moose in rut can become unexpectedly aggressive. Signs of aggression include laying back their ears, raised hair along their neck and licking their snout. Female moose don’t have the impressive antlers of their male counterparts, but don’t let that fool you into thinking they’re docile. A mother moose with her spring calf is quite possibly the most dangerous moose, and will use her powerful legs and sharp hooves to trample anything she thinks might be a threat to her babe. This includes the unlucky hiker or – more often – an unleashed dog.

Wild Aware Utah, a nonprofit offering education on how to reduce conflict with wildlife, recommends responding calmly to encounters with moose, talking loudly to let them know you’re there and leashing pets. Often the moose will move along on its own, uninterested in conflict. But if you find yourself in the bullseye of a moose’s ire, the best course of action is to back away slowly. And if you’re unlucky enough to be charged, get behind a tree or solid obstacle. Moose can run up to 35 miles an hour, which means you’re unlikely to outrun one, no matter how much adrenaline is fueling your flight.

Ruffed Grouse and the Christmas Bird Count

I set out this week to investigate why so many gifts in ‘The 12 Days of Christmas’ are birds. You know the song: there are swans a swimming, geese a laying, calling birds, French hens, turtle doves, and that partridge in the pear tree. Well, I never did find the answer. But what I did find was some interesting information about a native bird often incorrectly referred to as a partridge –a bird that is supremely well adapted to life in winter.

Ruffed grouse resemble partridges in that they are ground-dwelling game birds of similar size and stature. Their name comes from a collar of long feathers surrounding the necks of males who fluff them out when seeking mates in spring. The birds come in two color phases, differentiated mainly by their tail feathers, which can be either gray or chestnut brown. While not well understood, a grouse’s color phase seems to be linked to climate. Grouse with gray tails are more prevalent in areas defined by cold winters, while brown grouse are more common in warmer climates.

Now that snow is blanketing the landscape across much of their territory, the ruffed grouse is in its element. Harsh winters that adversely affect populations of other ground-dwelling game birds such as quail, pheasant, and turkeys, don’t seem to faze ruffed grouse. Their ability to survive is dictated by a number of special adaptations. The first is on their feet, where each winter nubby feathers called pectinations grow on the sides of the birds’ toes. Looking like strange combs, the bristles act as snowshoes, allowing the grouse to walk on top of even the softest snow. More special feathers grow on grouse legs like personal leg-warmers, and also near the bird’s beak, covering its nostrils. Scientists believe the feathered mustache enables grouse to breathe in warmer air than they otherwise would, thus keeping their internal temperature more stable.

Changes in weather bring about some changes in behavior as well. Warmer months find the birds resting in evergreens or thick brush. But in winter, when a foot or more snow covers the ground, grouse roost in the snow. The birds create small burrows which hide them from predators, offer protection from frigid winter winds, and keep them surprisingly snug and warm. Many a backcountry skier or snowshoer has been startled by a hidden grouse bursting noisily from its snowy lair.

The birds’ diet also changes seasonally from a summer sampling of green foliage, seeds, berries and insects, to the protein-rich dormant flower buds of trees such as aspen and birch. Grouse also won’t hesitate to eat the sweet flower buds of domestic trees like apples, and were at one time considered a pest in New England orchards. And so it’s actually not out of the question that within ruffed grouse territory, you might wake up one Christmas morning to find a ‘partridge’ in your pear tree.

Speaking of birds and the holiday season, it’s nearly time for the Audubon Society’s annual Christmas Bird Count. Over the next few weeks, tens of thousands of volunteers around the country will join in this 113-year-old tradition, collecting data on the types and numbers of birds living in their area. This data allows scientists to monitor and track populations over time and space. Participants can be seasoned birders, first timers, or anything in-between. In Logan, Ogden, Salt Lake, and Zion National Park, the count takes place Saturday, December 20th. Other locations around the state will host their events between now and January 5th. To find a count near you, visit birds.audubon.org and click on Christmas Bird Count. For the Stokes Nature Center and Wild About Utah, this is Andrea Liberatore.

The Geology of Canyonlands National Park

Baked by time like some multi-layer geologic tort, Canyonlands National Park in southeastern Utah features a landscape cut by canyons, rumpled by upthrusts, dimpled by grabens, and even pockmarked, some believe, by ancient asteroids.

Just outside of Moab rises a kaleidoscope of tilted and carved geology laid down over the eons. There’s the red and white Cedar Mesa sandstone, the grayish-green Morrison Formation, pinkish Entrada sandstone, and tawny Navajo sandstone, just to name some of the geologic layers. Stacked like pancakes, they help make Canyonlands the most rugged national park in the Southwest and, quite possibly, if you find yourself deep in the park’s Maze District, in the entire Lower 48 states.

In each of the park’s districts — Island in the Sky, Needles, Maze and Horseshoe Canyon — the remarkable effects of geologic time and its endless erosion on this sedimentary landscape rise about you.

If you could turn back the geologic clock, you would see the landscape flooded by oceans, crisscrossed by rivers, covered by mudflats and buried by sand. At various times through the millennia, the climate has resembled a tropical coast, an interior desert, and everything in between.

For hundreds of millions of years, material was deposited. Layer upon layer of sedimentary rock formed as buried materials were cemented by precipitates in the ground water. Each layer contains clues to its origin, such as patterns or fossils, which reveals the environment when it was deposited. For example, the colorful Cedar Mesa Sandstone occurred when periodic floods of iron-rich debris from nearby mountains inundated coastal dunes of white sand.

Along with sedimentation, movements in the earth’s crust altered surface features. The North American continent migrated north from the equator and the local climate and environment here changed dramatically.

Peer into the ragged maw of Canyonlands from the Island in the Sky District on the northern end of the park, and it’s no mystery how the park came by its name.

Spend the night at the Squaw Flat Campground in the Needles District and a morning hike into Chesler Park surrounds you with Creamsicle-hued minarets towering high above, like a king’s crown.

Though Canyonlands covers less than 350,000 acres, which is less than one-seventh the size of Yellowstone National Park, it feels much larger. No doubt it’s the park’s vastness and openness — you won’t find any forests here. Indeed, one old timer said that, “On a clear day, you can see the back of your own head.”

Spend a few minutes contemplating the natural forces, and the hundreds of millions of years that laid down these sediments and compressed these layers of rock. It’s really only recently that these layers have eroded to form the remarkable landscape seen today in Canyonlands National Park.
