Was googling various places in Wyoming to live when I came across this (Wind River is a real place):
Wind River Indian Reservation
"The
Wind River Indian Reservation, in the west-central portion of the
U.S. state of
Wyoming, is shared by two
Native American tribes, the
Eastern Shoshone and the
Northern Arapaho. Roughly 60 mi (97 km) east to west by 50 mi (80 km) north to south, the
Indian reservation is located in the
Wind River Basin, and includes portions of the
Wind River Range,
Owl Creek Mountains, and
Absaroka Range.
The Wind River Indian Reservation is the
seventh-largest Indian reservation in the United States by area, and the fifth-largest
[4] American Indian reservation by population. The land area is approximately 2.2 million acres (3,438 sq mi; 8,903 km2), and the total area (land and water) is 3,532.01 square miles (9,147.9 km2). The reservation constitutes just over one-third of
Fremont County and over one-fifth of
Hot Springs County.
[5]
The
2000 census reported the population of Fremont County as 40,237. According to the 2010 census,
[6] only 26,490 people now live on the reservation, with about 15,000 of the residents being non-Indians on ceded lands and the town of
Riverton. Tribal headquarters are located at
Fort Washakie. The Shoshone Rose Casino (Eastern Shoshone) and the Wind River Hotel and Casino, Little Wind Casino, and 789 Smoke Shop and Casino (all Northern Arapaho) are the only
casinos in Wyoming."
