Our permanent exhibit explores Sweetwater County's story. It spans millions of years, beginning with an ancient lake with prehistoric life forms that later fueled the county's major industries such as coal and trona mining. The history is diverse and chronicles a long pattern of human occupation, beginning with the Shoshone and Ute tribes.
Later, the first Rocky Mountain Rendezvous marked the beginning of regular occupation by white settlers. The Oregon, California, Mormon, Overland, Cherokee, and Pony Express all passed through Sweetwater County. Some of those early newcomers helped spur the development of the county's towns and cities, including its two major population centers, Green River and Rock Springs. Green River was the major railroad town due to the nearness of a water supply, while Rock Springs became the coal mining center of the county.
