Of the Native American population, 22% spoke a language other than English at home. The Wind River Indian Reservation established a 180,000-acre roadless area in the Wind River Range in the 1930s, several decades before the passage of the national Wilderness Act of 1964. The tribes have re-established populations of big game, such as moose, elk, mule deer, whitetail deer, bighorn sheep and pronghorn antelope, and have passed hunting regulations to conserve these species. In November 2016 the Shoshone introduced ten bison to the reservation, the beginning of what is planned as a 1000-head herd. They were the first bison to be seen on the Wind River Reservation since 1885. Area suited as buffalo habitat is estimated at 700,000 acres on the west side and another 500,000 acres on the north of the reservation. The Northern Arapaho established a bison herd in 2019. Facilities for tourism include hotels located at the Wind River Casino and the Shoshone Rose Casino. There are numerous cultural centers and interpretive displays at the Eastern Shoshone Cultural Center and library at Fort Washakie School, as well as the Northern Arapaho Experience Room at the Wind River Hotel and Casino. The Museum of the Rockies in Lander hosts weekly powwow dancing demonstrations during the summer. The Wind River Indian Reservation allows access for fishing and hiking for non-tribal members who purchase a tribal fishing license available from local retailers. The license allows access to fishing lands on the southern half of the reservation, including in the tribal roadless area that encompasses part of the dramatic Wind River Range. Hikers and mountaineers seeking the closest approach to Gannet Peak can hire a guide to drive into a trailhead. The reservation licenses contractors in Thermopolis to offer whitewater rafting and fishing outfitting in the spectacular Wind River Canyon. The Wind River Country, the wide expansion of land on which the Wind River Reservation resides, also provides opportunities for visitors to see and participate in important cultural experiences. Scheduled powwows are available to attend by the public. There are three larger celebrations throughout the year in the Wind River County, including the Eastern Shoshone Powwow in June, the Ethete Celebration in July, and the Northern Arapaho Powwow in September. Beginning on Friday nights, these ceremonies are an important aspect of Native American culture, that involve feasting, singing and dancing. Saturday and Sundays also have Powwow festivities.
