National Elk Refuge

The National Elk Refuge, located in Jackson Hole, Wyoming, was established in 1912 to provide winter habitat and preserve the Jackson elk herd. The Refuge is an integral component of the Greater Yellowstone Ecosystem; it is bounded by Grand Teton National Park and a wilderness area in the Bridger-Teton National Forest. The Refuge receives nearly 1 million visits annually. 
While elk are the primary reason for the refuge, other animals including bison, bighorn sheep, moose and deer are common in the winter. Small mammals such as coyotes, badgers, beaver and voles can also be seen. Birds are easily spotted year round, including hawks, eagles, ducks, trumpeter swans, and sandhill cranes.
