This photograph captures two American bison enduring the deep winter of Wyoming. The lead bison stands powerfully against the pale, snow-covered landscape, its massive coat crusted with frost and its face almost completely packed with snow from pushing through the ground in search of buried grasses. The second bison follows behind, partially obscured by the falling snow and shallow depth of field. Their dark bodies against the nearly white landscape emphasize both their size and their incredible ability to survive Wyoming’s harsh winters. What makes the image especially strong is the snow-covered face of the lead bison—it tells the story immediately. Bison use their enormous heads like plows, sweeping snow aside to reach vegetation beneath it.
