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.
RCAF Station Pennfield Ridge
Construction of the aerodrome began in the summer of 1940 after a suitable site was selected on a ridge high above the surrounding coastal plain of the north shore of the Bay of Fundy, east of the town of St. George. Proximity to a Canadian Pacific Railway line running between St. Stephen and Saint John eased the transport of building materials. General contractor Dexter Construction had 200 workers on the project by August 1940 and the runways were finished by November. The base was located southwest of the Camp Utopia, an army training facility for southwestern New Brunswick.
