Sulphur Mountain Cosmic Ray Station, a National Historic Site of Canada found atop Sulphur Mountain in Banff National Park, commemorates Canada's participation in the International Geophysical Year, during 1957 to 1958.

The National Research Council constructed a laboratory at the site in the winter of 1956–57.

The building was not visible from the Banff townsite as a condition of its construction.

[1] The station was run by Dr. B. G. Wilson with the help of two assistants [2] and was equipped with a standard IGY neutron monitor.
