Abstract: In September 1992, the Colorado Department of Transportation (CDOT) contracted the Colorado Department of Natural Resources, Avalanche Information Center (CAIC) to provide avalanche condition evaluations, forecasts and recommendations for avalanche· control and road closure, and other related services for U.S. Highway #550 in the San Juan Mountains of southwestern Colorado. Two CAIC forecasters are based midway along the 37mi/54Km avalanche-prone route, in the town of Silverton (Pop. 400; 9320'/2830m asl), from November I through May 1. This paper will describe project elements and forecasting methodology and will summarize weather, avalanche events and forecasting results for two winter seasons.
