The Air Force hired Morris Knudson Contractors in 1950 to construct the 638th AC&W Squadron. The 638th was operational until deactivation in 1960, when all removable property situated on the Forest Service and BLM lands was conveyed to Ferry County for offsite removal. It was stipulated that the County restore these lands to a state satisfactory to BLM and the Forest Service, which was done. Permits were then terminated or reassigned to the County in December 1962. GSA quitclaimed 48.08 acres to a private owner in April 1961.
The former operations area remains part of the Colville National Forest, and all operations area structures have been demolished, with the debris either hauled away or dispersed over the site. The cantonment and family housing areas stood unused until obtained by the Job Corps in February 1965. The Curlew Civilian Conservation Corps currently uses the site, having utilized and remodeled all remaining DOD buildings in the former cantonment area. The Forest Service and Ferry County maintain road access to all areas.
