SULPHUR MOUNTAIN COSMIC RAY STATION. Located at the top of Sulphur Mountain, the cosmic ray station was completed by the National Research Council in 1956, in preparation for International Geophysical Year (1957-1958) an undertaking involving 66 countries and a dozen scientific disciplines. The study of cosmic rays held a prominent place, with 99 cosmic ray stations (nine in Canada) in operation worldwide during IGY. Due to its high elevation Sulphur Mountain was the most important Canadian station. In 1960 the University of Alberta at Calgary took over the station, which was closed in 1978. The building itself was dismantled in 1981.
