METHODS OF AVALANCHE CONTROL IN WASHINGTON MOUNTAIN HIGHWAYS
The program report 8.5 presents a collection of papers on avalanche conditions and avalance prevention measures (on Washington mountain highways in general and the North Casade Highway in particular) covering various aspects of creep deformation and glide of the snow cover as they affect avalance defense structure design, reconnaisance of a proposed new highway route, and a continuing study of the relationship between synoptic winter weather patterns and the formation and distribution of snow avalanches in the Cascades. The Program Report 8.6 synthesizes the program of work carried out and presents conclusions based on the study. The Cascade Passes Avalanche Atlas (Part I) is presented which covers Chinook, Caynee, White and Snoqualmie Passes and was prepared on the basis of extensive aerial and ground reconnaissance.
- The two supplemental papers Program Report 8.5, Avalanche Studies (1973-1974), SS-3, July 1973; and Avalanche Atlas, Part I, Chinook, Cayuse, White and Snoqualmie Passes, August 1974.
