That's one serious difference between snowmobiling here and there. Same danger goes for back country skiing. Imagine snowmobiling up Washington?

Every snow storm we get leaves a layer of snow. Anywhere from six inches to several feet. Some are really unstable, and when additional accumulation builds up on top, the dry slab crust is not only dangeroudly avalanche prone, but very heavy, like blocks and slabs of concrete.

When snowmobiles became popular, people would race them up a slope. But our slopes tend to be steeper and much longer with more elevation gain. Sometimes they would go into a tree-free bowl and race up slopes of the bowl, literally cutting out the slabs of the avalanche that would bury them as soon as they weakend it from below. A big slab would lurch, then suddenly the whole thing would go. Being in the trees, in the forest is no safety. A big avalanche will plow into a forest and take it with. Imagine all those churning logs, trunks, and branches grinding up! A rolling crocodile or alligator could not tear apart and dismember you any better.

Your gentler, rolling hilly country would be wonderful for snowmobiling.

Our here at Jackson Hole is a run called Corbet's Couloir. Every year the ski area hosts a Kings and Queens event for the most outrageous entrance and descent line of Corbets. That can range anywhere from a ten to thirty foot drop, onto a 55 degree angle slope. If you fall, you wil slide all the way down the couloir totally out of control, leaving a yard sale as your poles, skis, and sometimes clothing is ripped off by friction of the snow.

Answer to your question. Yes, I did this.
