In the heat of the day, the elk will bed down in the snow just to stay cool. I have seen this first hand. When the snows start falling on a regular basis, usually mid-October to mid-November they will start moving down into the basins and meadows. A perfect example of this is the Milk Creek area in GM Area 211 in Colorado. If anyone is there the 3rd Rifle Season pray for snow a few days before the season begins. Elk will be all over the place for the next 3 or 4 days. It is very accesible and hunters will be very thick. Almost got a nice 6x6 there last year and I did get a Cow Elk there two years ago.
