The route, from Cascade Pass to Dome Peak, is generally remote, unmarked, and challenging, traversing rugged terrain and several glaciers.
The group consisted of four members of the Ptarmigan Climbing Club: Bill Cox, Calder Bressler, Ray W. Clough, and Tom Myers.
The second traverse was in 1953 and consisted of Dale Cole, Bob Grant, Mike Hane, Erick Karlsson and Tom Miller.
Miller took high-quality photos of the peaks, valleys, glaciers, and lakes, which were later published in a book by The Mountaineers.
The third successful traverse of the route was made in 1958 by a party led by photographer Ira Spring, with Coleman Leuthy, Ray and Marge McConnell, Peggy Stark and Russell Bockman.
