With
every step, I sank eight inches into wallowing fluff. Lifting each leg
awkwardly to take wide, encumbered strides, I was nonetheless glad the I wasn’t
post holing all the way to the leaf litter, over two feet down. A trackless
trail through the snowy woods will make anyone appreciate snowshoes pretty
quickly!
Five
inches of fresh snow, with more dancing in the air, had dissuaded me from
skiing, so I strapped the shorter and wider version of winter gear on my feet
for an evening walk.
Snowshoes
aren’t a new idea, of course. My plastic and aluminum models, with pop-up heel
props for climbing mountains, jagged metal crampons under the balls of my feet,
and easy-pull straps, are simply the most recent technologies. According to one
source, snowshoeing’s origins lie in the deep snows of Central Asia. Early
humans brought snowshoes across the Bering Strait when they migrated to North
America. Countless cultures have used them since--as a means of survival.
“This
is the snowshoe which is as necessary in winter as the canoe in summer. Through
the whole of North America, all the warriors, hunters, traders, travelers,
church goers, men, women and children, move about at that period in snowshoes.”
Wrote Johann Georg Kohl in his 1860 book, “Kitchi Gami: Life among the Lake
Superior Ojibway.” The snowshoes that Mr. Kohl writes about were made of bent
wooden frames laced with rawhide straps.
The
main benefit of snowshoes, of course, is that by distributing your weight over
a wider surface area, snowshoes provided mobility and flotation in deep snow.
But not everyone needs wood, metal, or plastic appendages to get the job done.
The earliest snowshoes, from at least a couple million years ago, are found
already attached to the Canada lynx and the snowshoe hare.
The
hare’s six-inch-long hind feet allow it to stay on top of deep snow. But the
lynx has feet four inches across, so it can follow and catch a hare.
With
less snow on the ground, however, lynx lose their advantage. It becomes harder
to compete with other mid-sized predators like pine martins,
fishers, and coyotes. The lynx’s own cousin, the bobcat, is its fiercest
competitor. These days, where you find bobcats, you just do not find lynx.
Lynx and hares don’t have a monopoly on snowshoe feet, though, and
other species are free to produce their own. Ruffed grouse grow projections off the
sides of their toes in winter, making them look like combs. The projections act
as snowshoes to help grouse walk across snow.
Many
other winter-active northern animals have extra-large feet, even if we might
not think of them as snowshoes. Fishers have large hind feet. Moose have huge
hooves when compared to a deer, and are more suited for deep snows. Wolves have
large feet, and often increase their surface area by splaying their toes in
deep snow. In March--the “snow crust moon” in Ojibwa culture—the wolves’ feet really
start to outperform the deer’s dainty toes.
For these animals, the advantage that snowshoes provide is a
matter of survival.
I huffed and puffed uphill through the snow for about thirty
minutes on my snowshoes before arriving back at home. When I left the house,
I’d been debating between going outside or taking a nap! Now, my blood was
flowing, my cheeks glowing, and I felt alert, calm, and in love with life.
Research has proven what I felt: to keep our brains at peak performance, our
bodies need to work hard. Exercise improves brain function, mood, and
attention, reduces anxiety, depression, and stress, and protects again the effects
of stress and aging.
My snowshoes might not help me catch dinner or escape predation,
but they provide me with access to the winter world, and give me tool for improving
my health and happiness.
For over 45 years, the Cable Natural
History Museum has served to connect you to the Northwoods. Come visit us in
Cable, WI, at 13470 County Highway M. The current exhibit, “Deer Camp: A
Natural and Cultural History of White-tailed Deer,” opened in May 2013 and will
remain open until April 2014.
