History
The Alsask Radar Dome is the last surviving dome of the Pine Tree Line, a Cold War era network of radar stations located across the northern United States and southern Canada. It was jointly utilized by the Canadian and American governments for monitoring Soviet activity in the North American airspace. It was a part of the CFD Alsask radar station. Construction of the dome began in 1961 and the dome was completed two years later. It was disbanded in 1987 and was designated a heritage property in 2002. The first floor contained the transmitter equipment and the second floor housed the receiver-associated equipment. Due to vandalism, the entrance stairs were removed.
Construction
The dome, which protects the radar equipment, is made of fibreglass. The tower itself is made of steel with metal cladding.
