1966-09-22
Summary
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 U. S. Geological Survey. [...]
