Vertical air photo of South Cascade Glacier and basin. The thin veneer of snow remaining on the glacier at this time is rapidly disappearing. The transient accumulation-area ratio is 0.40, which can be compared with the values of approximately 0.30 on September 30, 1966, and 0.15 on October 16, 1966, the end of the balance year. Although little snow remains on the glacier, accumulation patterns are still obvious in this photo. The strong influence of the prevailing western storm wind is indicated by drift patterns and by the predominance of snow remaining on the western side of the glacier (north to top of photo). Chelan and Skagit Counties, Washington. September 22, 1966. (Aerial view) Published as figure 7 in...

Album caption: South Cascade Glacier, North Cascade Range. Photo no. 8 was taken presumably in the autumn of 1928. Photo no. 9 was taken September 23, 1965. Note that the transient snowline is very near the same position in 1965 as in 1928, so that accumulation areas for both years are similar in size. The higher altitude glaciers and perennial snowfields shown in these photos have changed very little in size. However, because the exposed ice areas below the equilibrium line were much larger in 1928, ice loss would be much greater in 1928 than in 1965 even with similar meteorological conditions. Most of the mass loss in the 1928-65 interval occurred below the present equilibrium line. Chelan and Skagit Counties,...
