Bison Snow Mask Yellowstone National Park, Wyoming

This was on the drive from Mammoth out to Lamar Valley. Plenty of bison, but it was hard to be in the right spot to get a picture of their face. This one was swinging his head back and forth to push the snow out of the way while looking for food. Most of my shots at this spot had motion blur because of the dark conditions or his head was pointed down into the snow. - February 07, 2011 - 1/160 sec at f / 8.0 - 300 mm - ISO 200 - 44°57'17" N 110°30'21" W
