Sulphur Mountain Cosmic Ray Station National Historic Site

A cosmic ray station was built on Sulphur Mountain as part of the International Geophysical Year in 1957-1958 and Canadian scientists made important contributions to the research. Geophysicists studied cosmic rays and space particles entering the atmosphere from the station perched above the town of Banff, until 1978. Today, all that remains is the building's concrete foundation and a bronze plaque to commemorates the station's national historic significance.
