Today’s post includes some bison images made on my first day in Yellowstone NP. The bison, along with the elk, are really struggling right now in Yellowstone due to the snow amounts being a bit above normal and the recent extreme cold temperatures. Consequently, these animals are becoming quite stressed in their search for food. On our first trip into Yellowstone, the temperatures had not yet hit the -35°F mark, but were well on the way. In this sequence of images, you can tell by this bison’s breath that the temperatures were getting quite cold!
