The National Elk Refuge is located in the U.S. state of Wyoming and was created in 1912 to protect habitat and provide sanctuary for one of the largest elk (also known as the wapiti) herds on Earth. A total of 24,700 acres, the refuge borders the town of Jackson, Wyoming on the northeast while Bridger-Teton National Forest is to the east and Grand Teton National Park borders the refuge to the north. It is home to an average of 7,500 elk each winter. The refuge is managed by the U.S. Fish and Wildlife Service, an agency of the U.S. Department of the Interior.
Elk migrate from as far away as southern Yellowstone National Park and historically migrated to the present location of the refuge and further south into southwestern Wyoming during the fall, wintering on grassy plains that were both sheltered from weather and maintained less snowfall or snow depth than surrounding lands. During the spring, the herd would follow the retreating snows and growing grasses back into the Yellowstone National Park region. The original size of the elk herd has been estimated to have been in excess of 25,000. By the end of the 19th century, the town of Jackson had developed on important winter range and blocked off some of the migration routes used by the elk. The elk herd was severely reduced in size due to the hostile climate and lack of food supply, in addition to hunting pressures by both homesteaders and surrounding Native American tribes (Bannock).
A movement to protect the remaining herd and establish greater numbers was commenced in the early 1900s. When the Miller homestead was sold for $45,000 to the federal government, the refuge was established.
The elk herd survives the hard winters of Jackson Hole through a supplementary feeding program and a lottery based permitted hunting program, which is highly regulated. The elk have antlers which are shed each year and the Boy Scouts of America have been collecting the antlers under permit since the 1950s and selling them at auction under agreement that 75% of the proceeds are returned to the refuge, then used for irrigation of the grasses to maintain maximum natural food supply. Ten to eleven thousand pounds (4,500 to 5,000 kg) of antlers are auctioned each year. The increase in value has resulted in a commensurate rise in antler theft. 
The refuge also provides horse drawn sleigh rides to the public during the winter months so that visitors have the opportunity to see portions of the herd up close. The furthest consistent migration of elk to the refuge is currently from the southern portion of Yellowstone National Park,  making it the second longest ungulate migration in the lower 48 states. (The migration of pronghorn between the Green River basin and Jackson Hole in Wyoming is longer).
The refuge is nearly 25,000 acres (101 km2) of meadows and marshes along the valley floor, sagebrush and rock outcroppings along the mountain foothills. The largest single herd of bison under federal management, comprising 1,000 plus individuals, also winter on the refuge. Bighorn sheep can be found here, along with pronghorn, mule deer and even a few trumpeter swans along Flat Creek, which flows out of the refuge south into the town of Jackson. Rare sightings of wolf packs and grizzly bears have occurred, and a total of 47 mammal species and 147 bird species have been documented on the refuge.
The refuge has a lower elevation and much milder climate than the rest of the Greater Yellowstone Ecosystem, which is why so many elk and bison winter on it. Most of it is snow-covered from November until March, with the most snow on the ground being around a foot, which can happen in any month. Snowfalls are followed by sunny days, when some of the snow melts. South-facing slopes are free of snow for most of the winter.
