History

Crook County was established on October 9, 1882, by an act of the Oregon State Legislature. The county was named after General George Crook, a veteran of various battles against the indigenous peoples of Eastern Oregon in the middle of the 19th Century. The county was formed from territory formerly part of Wasco County, including the hilly region where the foothills of the Blue Mountains intersect the Cascade Mountain Range.

Access into the region at first was difficult, which discouraged settlement. The first effort to develop routes into the area was in 1862 when a supply train with cattle crossed the Scott Trail. This was also the first group of non-natives to spend the winter in central Oregon. The discovery and development of the Santiam Pass in the 1860s improved access into the area.

Prineville, incorporated in 1880 and then the only incorporated town in the county, was established as the county seat. This decision confirmed by the voters in the 1884 general election.

From the start cattle ranching has been one of the primary industries of the county, with huge herds grazing the countryside from the 1880s. Farming was also developed in certain valley regions friendly to agriculture.

Logging in the Ochoco Mountains and the timber mills that accompanied also greatly contributed to the economic and population growth of the county. The first recorded mention of a sawmill was made by George Barnes, speaking about the Swartz sawmill on Mill Creek, circa 1867.

Geography

The county is located in the geographic center of Oregon. According to the U.S. Census Bureau, the county has a total area of 2,987 square miles (7,740 km2), of which 2,979 square miles (7,720 km2) is land and 8.2 square miles (21 km2) (0.3%) is water. The largest body of water in Crook County is the Prineville Reservoir. The county has been reduced from its original size of 8,600 square miles (22,000 km2) by the creation of Jefferson County in 1914 and Deschutes County in 1916. The present boundaries were established in 1927.

The oldest geological formation in Oregon is in the southeastern corner of Crook County, near its boundary with Grant County. This formation is an outcropping of Devonian limestone created from a larger reef when most of Oregon was covered by water.
