Bison Forging Ahead in Snow

From the U.S. Department of the Interior:

Walking in the deep snow can be difficult. Bison use their strong necks to
push forward and make a path, their shaggy faces keep them from getting too cold and they take turns leading the way. These adaptations allow them to
thrive in the harsh winter conditions of Yellowstone National Park in
Wyoming. Photo by Jim Peaco, National Park Service.— at Yellowstone National Park.
