EVALUATION AND PREDICTION OF AVALANCHE HAZARD, SAN JUAN MOUNTAINS, COLORADO
A significant snow avalanche hazard exists along U.S. Highway 550 between Coal Bank Hill and the town of Ouray, Colorado. A statistical avalanche forecast model has been developed based on discriminant analysis in order to predict avalanche activity. The data base, which contains meteorological, snowcover and avalanche variables, includes seven winter seasons. Specific data summaries for the 1976-1977 and 1977-1978 winters are included. Particular attention is given to accurate and detailed compilation of avalanche events within 214 avalanche paths. The prediction model is tested against actual avalanche activity observed during specific storms.
