As a celebration of a milestone birthday for m, we took a weekend in Jackson Hole.  Part of the visit was a trip into Yellowstone on a snowcoach.  There isn’t much in the way of wildlife in Yellowstone during the winter.  The bears are hibernating and the moose and elk have all headed down to lower levels.  Some bison have also headed down but other stay, attracted by the thawed areas around the hot springs.  We saw a few of them working their way through snow covered grounds using their powerful necks to move snow away from the plants underneath.
