History and General Information 

Crook County was formed from Wasco County in 1882 and named for Major General George Crook, U.S. Army. Geographically, the county is in the center of Oregon. It is unique in that it has only one incorporated population center, the city of Prineville founded in 1868. Prineville’s colorful past was the scene of tribal raids, range wars between sheep and cattle ranchers and vigilante justice. Other communities in this sparsely settled region are Powell Butte, Post and Paulina.

Thousands of hunters, fishers, boaters, sightseers and rockhounds are annual visitors to its streams, reservoirs and the Ochoco Mountains. Rockhounds can dig for agates, limb casts, jasper and thundereggs on more than 1,000 acres of mining claims provided by the Prineville Chamber of Commerce. Major annual events include the Prineville Rockhound Powwow, Crooked River Roundup, Crook County Fair, Old Fashioned Fourth of July Celebration, High Desert Celtic Festival and the Lord’s Acre Sale.
