Old Man Winter Sepia
If there ever was a portrait of old man winter in animal form, this is the one. This bison seemingly poses for his portrait of winter fortitude demonstrating his hearty nature. Bison are able to withstand sub-zero temperatures for weeks at a time, and they use their massive shoulder hump as a tool, enabling them to use their heads to move snow away from their winter forage. This makes them masters of snow and ice, able to survive during the harsh winter months.
