I had wanted to see this and got the chance on April 2, 2016. This dome was part of the DEW (Distant Early Warning) Line to give advance warning of a Soviet attack. There are a number of abandoned buildings in Alsask that used to house military personnel. Alsask (Alberta/Saskatchewan) is right on the border. The town is in Saskatchewan, the cemetery is in Alberta. The RCAF base (Royal Canadian Air Force) ceased operation in 1987.
