Caribou Air Force Station
Caribou Air Force Station, also known as North River Depot and East Loring, is a defunct Air Force Station that operated from 1951 until some time when it was absorbed into Loring Air Force Base in 1962. It was located in Limestone, Maine, adjacent to Loring. Between 1951 and 1962 Caribou was an Operational Storage Site for Air Materiel Command (AMC-OSS), one of five in the United States, and the weapons storage and maintenance facility for Loring alert aircraft.
Cape Sarichef Airport
The airport was built in 1958 to support Cape Sarichef Air Force Station, a Cold War United States Air Force Distant Early Warning Line radar station. The station was operated by Detachment 3, 714th Aircraft Control and Warning Squadron based at Cold Bay Air Force Station, near Cold Bay, Alaska. The radar station was inactivated in September 1969, ending military use of the airport. The Air Force remediated the site around 2000, removing all abandoned military structures and returning the site to a natural condition.
