Snowshoes

Imagine yourself living in Utah hundreds of years ago – before cars, before horses, before European influences. Summers provide you with abundant game and a multitude of plants for food and other materials, but the winters are harsh and full of snow. How did Native Americans manage to survive winter without modern amenities like snow plows and grocery stores? These hearty individuals owe their ability to hunt and travel in our snowy climate to one important tool – the snowshoe.

Snowshoes have been a part of life for humans in cold-weather climates for at least 6,000 years. From what historians can tell, people living in central Asia learned to strap thin planks of wood to their feet in order to help them travel through deep snow. Snowshoes work by increasing the surface area of the wearer’s foot, which distributes his or her weight across more snow – allowing them to basically float on top of the snow.

From this common ancestor in central Asia, both snowshoes and skis arose. Over the years, people began to spread out and move to new locations. Those who went west, into Europe, eventually developed the ski and those who went east across Siberia and into the Americas developed the snowshoe. The early snowshoes used by Native Americans were constructed of a wooden frame which was laced with babiche, un-tanned animal hide.

While we will likely never know why that first person decided to strap a plank of wood to their foot, perhaps they took their cue from Mother Nature. You see, humans are not the only ones who have figured out how to keep ourselves afloat on snow – some members of the animal world have too, and Utah holds two standout examples: the aptly named snowshoe hare and the Canada lynx. Both of these animals have extraordinarily large feet, which act much the same as our snowshoes, distributing the animal’s weight across a larger surface area.

Perhaps it’s no coincidence that both snowshoe hares and Canada lynx share this amazing adaptation. These two species are closely connected to each other in a special relationship: that of predator and prey. Leaving us to ponder the question: whose snowshoes came first, the lynx or the hare?

Huddling for Warmth

When temperatures dip below freezing and wind hurries on its way, we often find ourselves looking for another warm body to huddle near and share heat. Children snuggle into laps and dogs lean close.

Many animals huddle to stave off the cold. Species that are strong individualists in balmy seasons seek warmth from a group when temperatures drop. Many non-colonial rodents will share a den come winter.

[Kevin Colver recording: Songbirds of the Southwest Canyon Country]

Pygmy nuthatches jam themselves tightly together into tree cavities as do flying squirrels. Through the winter, worker honeybees huddle tightly around a central patch of wax comb where developing larvae are growing. The larvae die if temperatures drop below 83 degrees, so a living blanket of worker bees shivers to generate the heat equivalent to a 40 watt incandescent bulb.

An animal loses heat in direct proportion to its surface area. By huddling together, each animal reduces its exposed surface area. This in turn allows them to reduce their metabolic rate and so conserve energy at a time when food can be scarce or inaccessible.

Nests or dens occupied by numerous individuals can be much warmer than ambient. A snow covered lodge with at least 2 beaver occupants can be as much as 35 degrees warmer than the outside air temperature. A study of taiga voles showed that underground nests containing 5 to 10 residents remained 7 to 12 degrees warmer than the surrounding soil and up to 25 degrees warmer than the air above. Individuals take turns going out to forage so their nest remains toasty.

Living in close proximity does have its problems. Disease and parasites are readily transmitted in tight quarters. Local food competition could potentially lead to hunger or starvation. Predators may more easily discover prey in groups. But for many animals, the advantages of huddling for warmth far outweigh the risks during our chilly winter months.

Utah, the Red State

Hi, I’m Holly Strand for Wild About Utah

Straddling the four corners region is a massive geologic province known as the Colorado Plateau. Varying from 5 to 10,000 feet in elevation the region covers an area even larger than Utah, and is composed of thick horizontal layers of sedimentary rock. Wind and water have whittled Plateau rock into dramatic cliffs and steps as well as fanciful domes, towers, turrets, and arches. A predominance of red bed deposits in the central area of the Plateau has prompted the nickname “red rock country.”

So what’s behind these spectacular red hues? The color of rock is primarily influenced by trace minerals. The red, brown, and yellow colors so prevalent here result from the presence of oxidized iron–that is iron that has undergone a chemical reaction upon exposure to air or oxygenated water. The iron oxides released from this process form a coating on the surface of the rock or rock grains containing the iron.

Just think of what happens to a nail when you leave it outside. Upon prolonged exposure, the iron in the nail oxidizes and rust is formed as a coating on the surface of the nail. So basically what we have in red rock country is a lot of rusting sandstones and shales. Hematite is an especially common mineral form of iron oxide in Utah, the name coming from the Greek word “heama” or red blood. It only takes a tiny bit of hematite make a lot of red rock.

Certain rock formations in Utah are particularly well-known for their beautiful reddish colors. The Permian Period gave us Organ Rock shale which caps the buttes and pinnacles of Monument Valley. The deep ruddy browns of the Moenkopi formation were formed in the Triassic. In the early Jurassic, eastern Utah was a vast sea of sand with wind-blown dunes. These dunes became the red bed deposits of the Wingate Formation which today forms massive vertical cliffs. Entrada sandstone, from the late Jurassic, forms the spectacular red, slickrock around Moab.

So now you know what I’m thinking of when I hear Utah referred to as a Red State. I’m picturing the extraordinary splendor of the red, orange and rust- brown rocks that help to form the massive geologic layer cake in the south and east of our state.

Sleeping Winter Away

As Utah’s blanket of snow grows thicker and cold temperatures set in, some of our furred friends quietly retire for the winter. Gone are the marmots that basked on sunny slopes, the bears that browsed in the forests, and the bats that winged silently overhead.

Animals have a number of different strategies to help them survive in winter. Some, such as hummingbirds, migrate to a more temperate climate. Some have special adaptations that allow them to withstand cold temperatures such as mink, which grow wonderfully thick winter coats. And some, such as marmots, bears, and bats, simply find a cozy place to sleep away the winter.

The general term for this period of inactivity is “dormancy,” which includes more specific terms such as “hibernation” and “torpor.” During this time, an animal’s heart rate, breathing rate and metabolism slows down considerably. Contrary to popular belief, most of the mammals that hole up for the winter do not actually hibernate. The term hibernation applies to only a small portion of our Utah mammals – a few species of bats and some rodents like the marmot. True hibernation means that an animal’s metabolism turns off to the point that its body temperature nearly matches that of the environment around it. And in winter, this means that body temperatures can drop to nearly freezing. Hibernating animals become unresponsive to environmental stimuli such as loud noises and being touched, and it takes hours and lots of energy for them to finally awaken.

In contrast, consider the bear, which does not technically hibernate, but instead enters a state called torpor or ‘winter lethargy’. A bear’s body temperature does decrease during this time but never approaches freezing. Bears also remain semi-active occasionally moving about in their dens, or even giving birth and tending to their newborns. Other animals that become largely inactive in winter but do not fully hibernate include skunks, raccoons, and opossums. These animals can respond very well to environmental stimuli and can resume their full abilities in less than a minute if disturbed – something to keep in mind in case you stumble across a bear’s den this winter.
