With our recent snowstorms I have been thinking about the power of observation. My wife noted some tracks out in the backyard and asked what they were. Most likely a cat I said. I went on to explain that cats tracks seem to meander more than dogs do.
There are other observations to be made in the snow as well.
Snow will obviously melt on south facing slopes, but also on the south western side of exposed boulders.
There are ways to tell some really specific things about the weather, both on the ground and up in the atmosphere, but closely observing snowflakes.
Since wind can be a killer in the white months, when looking for a shelter, look around for prevailing wind direction. You will not bare patches, drifts and "frozen waves" or "dunes."
