Crook County

Crook County is an administrative division in northeastern Wyoming covering a large expanse of land that includes the Missouri Buttes and the Bear Lodge Mountains. The county encompasses several small towns and settlements spread across the region.

The county was established in 1875 by the Wyoming Territory legislature and named after General George Crook, a commander during the Indian Wars period. This early founding shaped the settlement and development of northeastern Wyoming.

The communities here maintain strong connections to German, English, Irish, and Swedish roots. These heritage ties shape the local social fabric and traditions that visitors encounter in small-town gatherings.

The main towns of Sundance, Hulett, and Moorcroft are connected by Interstate 90 and several US highways for easy access. These road networks make it straightforward to reach larger cities like Rapid City and Gillette.

The Belle Fourche River marks Wyoming's lowest elevation point as it flows from here into South Dakota. This geographically significant waterway creates a natural boundary between the two states.
