Canadian, UK, and French military personnel, primarily pilots and aircrew from Canada learn how to build snow caves at the Canadian Forces Crystal City training facility near Resolute Bay, Nunavut. Snow caves are one of several types of shelter that soldiers must learn to build in order to survive in the Arctic in the event of an emergency. The soldiers in this course spent an entire week living and sleeping outdoors in temperatures below minus 50 degrees Celsius (-58 F).
