A detailed description of plans for highway maintenance through avalanche areas across Rogers Pass, British Columbia. Approximately 120 avalanche paths in 24 miles of highway are classified into four categories according to frequency of avalanche occurrence. A description of preventive or control measures for each category are suggested. Avalanche forecasting and warning procedures are explained together with plans for artificial release of small slides to prevent a disastrous avalanche. Maps and photographs depict the scope of the project.A formal discussion of the paper is presented by W.M. Borland, who cites technical problems of avalanche control on highways leading over the Rocky Mountains of Colorado. Avalanche control by artificial release are discussed. Comparisons of Colorado conditions are made with those conditions found on Rogers Pass.
