No matter what
the temperature, thrashing around produces a lot of body heat and moisture, and
it is imperative that this be controlled and disposed of properly or it will
turn to ice with all sorts of evil consequences.
If you are going
to be active in the cold, the best mode of dress is a loose, layered one.
Fishnet underwear, which provides good insulation because of the air spaces but
lets heat and moisture radiate away from the body, is a good foundation
garment. Wool makes the best next layer because, unlike cotton, it dries from
the inside out and breathes (passes moisture) very well. The outer layer should
be thin, designed to keep moisture and wind out. Overall, a long flowing
cagoule-like mountaineering parka is good. Under these layers, heat and
moisture rise, and the top of the costume, around the hood of the parka, can be
easily opened or closed to accommodate this. When you start building up too
many BTUs and too much moist air, you can open the throat and let it escape,
and when you have cooled down, you close the throat and start building up the
heat. For the feet, rubber boots with leather uppers are the best.
This is how we
remained warm, more or less, through the worst week of winter weather anyone
around the Black Forest could remember. As to questions about where was all our
stylish, puffy, down gear of the sort smiling models display on the covers of
outfitters' catalogs, it was where it belonged, stuffed in our packs, waiting
to be used at night when we stopped and when we slept. There is not much that
provides better and lighter insulation than down because of its properties for
trapping air between the little feathers. However, despite all the down being
sold in such arctic areas as San Diego and Houston, it has severe limitations.
If it is squashed flat, say under a pack, it can't trap air and does not
insulate. For the same reason it loses its clout if it becomes wet. Down is
great for sleeping in or standing around in, but otherwise it is not so hot. In
a recent spree of false role playing, and as a status symbol, it has been
misused, oversold and overbought.
SNOWSHOES
On the right kind
of trail you can lope along on snowshoes, getting a pleasant, bouncy,
trampoline effect from the webbing. You can bound down an open slope in big
leaps, achieving somewhat the sensation of rappelling without ropes. Otherwise,
there is nothing very sporty about snowshoeing, which is really nothing more
than awkward walking. Also, it is not a high-skill activity. Anyone who can
simultaneously walk and chew icicles out of his mustache can learn to snowshoe
passably in half an hour or so. Like other ordinary things such as crawling,
planting bulbs or sawing wood, it gets easier the longer you do it, but the
basic act is not difficult.
Snowshoes have
been around for a few thousand years and nobody has yet invented a ski, sled or
snowmobile that better accomplishes what they are intended to
accomplish—getting a man through deep snow and over rough terrain. Because
there are a lot of different snow conditions, a great variety of snowshoes have
evolved. There are, for example, almost circular ones, often called bear-paws,
which while a little awkward are great supports in very deep, soft dry snow. At
the other extreme are long narrow six-foot shoes with extended wooden tails on
which you can travel very fast in hard snow and open country, say, across
prairies or tundra. Both pairs of my shoes are of a general type developed and
used in woodlands. They are less round and provide less support than bearpaws,
are rounder and not so fast as the narrow, arctic type, and have short tails
and are more maneuverable than either of the extremes. The larger pair is laced
with rawhide and the other with neoprene ribbons. Much as I hate to admit it,
the neoprene is more practical because it does not take on water and does not
have to be periodically varnished, but I have always preferred rawhide and,
somehow, it feels better underfoot.
Sentiment aside,
Sam and I thought that we might have snowshoe problems in our travels in the
Black Forest. The larger rawhide shoes will keep about 240 pounds on the
surface of the snow. The neoprenes are rated at about 200 pounds. Obviously Sam
had to use the bigger ones, but with a pack he was going to be 20 pounds or so
overweight, and I was going to be about as much over the best load limit on the
neoprene shoes. If we got into very deep light snow we might have some hard
going—as in fact we did.
There are a
series of open meadows extending from Potato City back into the forest. The
wind had graded and packed these snowfields, and we moved across them smartly,
cruising along on the crusty surface. However, there was only about half an
hour of this easy going. In the woods there was a three-foot snow cover on the
flat, but frequent and extensive drifts were twice as deep or more. Also,
because it had been so cold, the snow remained very light and fluffy. On our
overloaded shoes we sank six inches to a foot with every step. Obviously this
was better than sinking in three to six feet, as we would have if unshod, but
it still promoted slowness and exhaustion.
Woodland shoes
have an upward tilt on the prow. The purpose is to keep the shoe pointing up
through the snow, preventing the tip from digging down diagonally into drifts
and stopping or tripping its wearer. In effect, these shoes are flattish
scoops. Even properly weighted you expect to sink a few inches, and with each
step some snow collects on the scoops. Getting rid of it accounts for the
customary snowshoe gait, which is more a glide than a stride. On each step the
foot is shuffled forward and then given a little shake to kick off the snow.
When you have a six-inch dollop of snow to clear, as we did most of the time,
you have to lift your foot higher to get out of the hole you have dug and then
kick harder. Stumbling and fatigue result.
All of these
problems only really concern the first person in a party because he packs down
the snow, and anyone who follows can step in his tracks and ride along nicely
on the surface. In the flat, better packed snow, one of us might be able to
break trail for a quarter of a mile or so. In the drifts, ascending and
descending the mountainsides, we sometimes could keep going for only 20 yards
before we were gasping and heaving and had to stop to open our parkas to let
off steam and make way for the other to have a go at trailbreaking. It is a
situation in which strength is far more valuable than expertise, and as the
days went on Sam took longer and longer turns in front. It was the horse's
edge—or penalty.
