City in Wyoming, United States
Riverton is a city in Fremont County, Wyoming, United States. The city's population was 10,682 at the 2020 census, making it the most populous city in the county.
History
The city, founded in 1906, is an incorporated entity of the state of Wyoming. The community was named Riverton because of the four rivers that meet there.[5] The town was built on land ceded from the Wind River Indian Reservation, a situation that often makes it subject to jurisdictional claims by the nearby Eastern Shoshone and Northern Arapaho tribes.
A legal ruling on November 7, 2017, by the 10th Circuit Court, ruled again in the EPA reservation boundary dispute. Though the decision was complex, the 10th Circuit Court answered plainly. Riverton is not on the reservation. The 10th Circuit's decision is now official and final after the 10th Circuit Court of Appeals 2017 ruling. The Tenth Circuit Court of Appeals reversed the decision of the EPA, and held that the land had been ceded in 1905 by an Act of Congress. This ruling ends the dispute, bringing the debate and controversy to an end.[6]
Riverton Regional Airport (now Central Wyoming Regional Airport) is home to a National Weather Service Forecast Office and NEXRAD radar site which is responsible to cover all of western and central Wyoming.
The Chicago & Northwestern Railway completed an extension of the "Cowboy Line" through to Lander which is roughly 22 miles west of Riverton. Plans were to continue the line west from Lander. In 1972, the end of the line was moved from Lander and the new terminus of the line was in Riverton. Services were then discontinued in Riverton in the mid-1970's as the line was slowly dismantled west of Casper.
