Given the relatively balmy temperature of 19F today, I decided to venture out and play in the snow. First activity: shoveling a driveway, something I haven't done in about twenty years. A winter storm moved in this morning and is expected to drop about eight inches of snow.
I took a short hike up the old park road from Gardiner, and encountered four elk descending from a ridge into a sheltered basin. 
Only the northern part of the park (where I live) is at a low enough elevation to support significant winter populations of elk; the NPS estimates Yellowstone supports 30,000 elk in summer, which drops to between 15,000 and 22,000 in the winter.
