Yellowstone National Park, Wyoming
                                                                   
Winter in the northern rockies can be a difficult time for wildlife.  Bison are well prepared for the hardship with their thick winter coats and their ability to use their large heads to clear snow in search of buried grasses.  The thermal features of Yellowstone do provide warmth and clear ground which the bison readily inhabit to make the passing winter more bearable. However, this large bull simply waits out the storm as the snow piles up on, and around him, while his winter coat insulates him from the wind and cold.   Bison once numbered over 30 million animals in North America, but Yellowstone is now home to the last wild herd in America.
