Riverton | USA Wyoming

Riverton is an incorporated city in Fremont County, situated at the confluence of the Big Wind and Little Wind Rivers. Defined by its location within the exterior boundaries of the Wind River Indian Reservation, it is a center of agricultural commerce, tribal administration, and regional education. It serves as the primary retail hub for Central Wyoming.

Historical Timeline

Inhabited by the Shoshone and Arapaho peoples. A critical historical event occurred in 1838 when the site hosted the last Great Rocky Mountain Fur Rendezvous. Founded in 1906 following the withdrawal of lands from the reservation under the Homestead Act. Unlike many Wyoming towns, Riverton was not a railroad creation but an irrigation-planned community designed to support high-desert farming. In the 1950s, the city experienced a massive boom following the discovery of uranium in the nearby Gas Hills. In 2026, the city is a focal point for Tribal Economic Development and aerospace research.

Facts & Legends

Riverton is one of the few cities in the U.S. that was literally "born in a day" during the land rush of 1906. Historically, it was the site of the "Uranium Capital" offices during the Cold War. A local legend involves the "Rendezvous Ghosts," spirits of early mountain men said to be heard near the confluence of the rivers on mid-summer nights. Another legend concerns "The Riverton Treasure," a rumored cache of gold coins buried by a stagecoach driver near the Little Wind River during a 19th-century robbery.
