Hector Glacier is located in Banff National Park, Alberta, Canada. The glacier is on the north slope of Mount Hector and extends northward for 3 km (1.9 mi). In 1938, a large mass of the glacier broke off and covered the valley below with ice up to 60 m (200 ft) thick. The ice mass destroyed everything in its path and this is only the second known glacier hazard to have been recorded in the Canadian Rockies.
