Fort Caspar Museum and Historic Site, located in Casper, collects, preserves and exhibits artifacts concerning the social and natural history of Fort Caspar, the City of Casper and central Wyoming. Exhibits include Native American artifacts, western art, and exhibits relating to the history of the area.

This unique historic place preserves and interprets one of America's most important locations in the history of westward expansion and Indian resistance. Established in 1834, Fort Laramie began as a fur trading post. By the 1840s, wagon trains rested and resupplied here, bound for Oregon, California and Utah. In 1849 as the Gold Rush of California drew more westward, Fort Laramie became a military post, and in 1876, Fort Laramie served as an anchor for military operations, communication, supply and logistics during the "Great Sioux War." Fort Laramie closed in 1890.

The Uinta County Museum is located in the historic Carnegie building, completed in 1906. A lovely example of Classical Revival architecture, the building was designed by New York architect Albert Randolph Ross (who also designed a Carnegie Library in Washington, D.C.). In 2008, an expansion of the building was completed. Designed by Jackson architect Kurt Dubbe, the new building echoes the historic features of the original structure. Their mission is to collect, preserve, and interpret the history of Uinta County and the surrounding region, and to make our collections available to the public.

The Museum reflects the history of Crook County. Permanent exhibits include Indian artifacts, cowboy artifacts and pioneer artifacts dating from 1875. Also included is furniture from original Courthouse, 1888, the Sundance Kid was on trial here; a Vore Buffalo Jump Diorama and display; a Custer Trail diorama showing the route taken by Custer through Crook County and the Black Hills; and Crook County photographs, brands, and local artifacts. The Museum has a complete microfilm collection of Crook County newspapers.
