You don’t see bison flake because of a little snow. During a winter storm, bison face the cold and take the winter elements head on, conserving energy as they hunker down and wait for snowstorms to pass. Yellowstone National Park in Wyoming is the only place where bison have lived continuously through American history, and they have a good handle on surviving tough winters. Photo by Jacob W.
