Bison frequent the area around Dragon’s Mouth Spring in Yellowstone to feed where it is too warm for the snow to accumulate.

How do bison survive the snowy Jackson Hole winters? Well, having a big head helps! Bison can use their heads as a snowplow in winter, swinging it from side to side to sweep aside the snow on the ground.

The National Elk Refuge in Wyoming works to provide, preserve, restore, and manage winter habitat for the nationally significant Jackson Elk Herd and habitat for endangered species, birds, fish, and other big game animals (like these Bison pictured above), and provide compatible human uses associated with the wildlife and wildlands.

The National Bison Range in Montana is administered by the U.S. Fish and Wildlife Service as part of the National Wildlife Refuge System. It was established in 1908 and is one of the oldest Wildlife Refuges in the nation. As its name implies, the Refuge was established to support a population of American bison. It is home to about 350-500 of these animals. Other large wildlife found on the Range include elk, white-tail and mule deer, pronghorn antelope, bighorn sheep and black bear. Because of its open grasslands, the Bison Range is a place for the public to enjoy some excellent wildlife observation and photography.
