Established in 1880 as Camp Spokane, this U.S. Army post ensured relative peace between nearby Indian reservations and the increasing number of settlers to the south. The post was transferred to the Indian Bureau in 1899, and for the next 30 years it served as an Indian boarding school, tuberculosis sanatorium, and hospital. Time has reduced most of the original 45 buildings to silent foundations, but the brick guardhouse survives.
