At the peak, step back in time and experience the Sulphur Mountain Cosmic Ray Station.
The cosmic ray station was completed by the National Research Council in 1956. The study of cosmic rays held a prominent place, with 99 cosmic ray stations (nine in Canada) in operation worldwide. Due to its high elevation, Sulphur Mountain was the most important Canadian station.
The station was closed in 1978.
