A column from yesteryear.
Snow, for
all of its inconveniences—driving challenges, shoveling, and slippery
walking—also has a lot going for it. The obvious of course is the beauty
of a snowfall and the wonders of the countryside transformed from the drabness
of late fall’s browns and grays to a world of white. Snow also provides an
opportunity to ski and snowshoe and go sledding. And a chance to build a
snowman or a snow fort or maybe even experience a friendly snowball fight.
I did a
little digging, no pun intended, into the characteristics of snow, and came up
with some interesting information, at least interesting to me.
Snow is
not always white. It may also appear blue especially on a cold winter
night when the moon is out.
Most of us have experienced
how sound changes after a fresh snowfall. Sound is absorbed by snow,
muffling it. But when the snow becomes hard and crusty, the opposite
happens. Sound bounces off the snow’s surface and travels farther. Of
course we all know the sound packed snow makes when we walk on it, especially
on cold days when it creaks and crunches, and sounds like it is protesting our
presence.
Snow is also a great insulator. Fresh
snow is made up of from ninety to ninety-five percent air. Many animals
know about snow’s insulating qualities as they burrow into snow to keep
warm. Farmers know this as a good snow cover protects crops such as
alfalfa from “winter kill.” A good snow cover also keeps my septic system
from freezing—not a good thing as it happened a few years ago when we had a
stretch of below zero weather and no snow.
Snow also stores water. Ten-inches of
snow may equal one-inch of water. Or ten inches of snow could contain as
little as one-tenth inch of water. It depends on whether a snowfall is
enhanced by moisture from the Gulf of Mexico, or comes from the dry plains of
Canada.
This is probably more than you wanted to know
about snow, but I find it all interesting as we plow on into the new year with
many more snowfalls to come.
THE OLD
TIMER SAYS: Let it snow, let it snow. Nothing much we can about it anyway.
