Dubois, the county seat, and Spencer sit along Interstate 15 between Idaho Falls and the Montana line, surrounded by rangeland, sagebrush plains and the mountains of the Continental Divide.
Clark County Economy & Jobs
Ranching and agriculture are the mainstays of Clark County's economy. The U.S. Sheep Experiment Station, operated by the USDA's Agricultural Research Service, is located near Dubois, and Spencer is known for its opal mines. Highway services along Interstate 15 and work in larger towns to the south support other residents.
History of Clark County
In 1864 stagecoach stops on the route between Salt Lake City and the Montana mining towns were established at Beaver Canyon and Dry Creek, the settlement later renamed Dubois in 1892. The Utah and Northern Railway reached Beaver Canyon in 1879, and that settlement relocated to Spencer in 1897. The Battle of Camas Creek, part of the Nez Perce War, was fought at Camas Meadows near Kilgore. Clark County was created from Fremont County when Governor D. W. Davis signed the bill on February 1, 1919, and was named for state senator Sam K. Clark, an early pioneer on Medicine Lodge Creek.
