• Description:
  This study conducted an inventory of existing avalanche paths along Colorado Highways. Information was collected on the size and type of each avalanche path, the historical frequency of avalanche occurrences, the number of avalanche tracks, the length of highway exposed, the volume of traffic on the road, the traffic peak characteristics, the speed of traffic and the consequences of an avalanche encounter with a vehicle. This information was used to generate an Avalanche Hazard Index (AHI) for Colorado Highways. The concept of the AHI has been used in the past as a quantitative measure of the avalanche hazard to traffic. The AHI values calculated in this study are considered relative values and can be used to compare the hazards of particular avalanche paths or avalanche prone routes in Colorado.
