Our third morning in Yellowstone National Park dawned colder than our first couple of days here. We were hoping to find Bison with snow crusted on their coats and we came across a few bulls plowing through the snow to find something to munch on. They were so intent on finding sustenance that they didn’t lift up their heads often and I was lucky to get a few shots before he plunged back into the snow, tossing his head from side to side clearing away the snow from what was left of the grasses beneath it.
