Abstract: The 5 Mountain Parks Highway Avalanche Study was completed for the Canadian Parks Service in 1993. The routes studied included Rogers Pass and Kicking Horse Pass, (Trans Canada Highway), the Radium Highway, the Icefields Parkway, the Maligne Lake Road, the Sunshine Road, the Minnewanka Road, the Field Road, and the Emerald Lake Road. Each of the avalanche programs on these routes had evolved somewhat independently within local parks jurisdictions. The Canadian Parks service objectives were to ensure their future operations were undertaken in a cost effective manner which was commensurate with the hazard on each route and the common practices of North American Highway operations. The methodology of the Five Mountain Parks Highway Avalanche Study included: • Calculation of the Avalanche Hazard Index & Residual Hazard Index. • Evaluation of the economic impacts of avalanche closures. • , Identification of acceptable closure levels. • ' A survey of practices in North American highways operations. • Evaluation & costing of present programs. • Identification, hazard evaluation & costing of future program options. The objectives of the current paper are to provide examples of the use of avalanche hazard index, summarize the practices identified in North American operations and outline the conclusions of the Five Mountain Parks Study.
