1957-08-30
Summary
Upper reaches of Nisaqually and Wilson Glaciers as seen from station 13 on August 30, 1957. Most of exposed bedrock areas marked in photo no. 18 are now covered by Wilson Glacier. Glacier surface at profile 3 is only 3 feet (1 m) higher than in 1949, but near left edge of picture it probably is about 60 feet (18 m) higher because at profile 2 the ice level rose 97 feet (30 m) from 1949 to 1957. The crevassing appears much coarser (rougher) now and extends to the east edge of the glacier. Exposed face of the ice field above the cliff is thicker. The falls at far left are nearly dry (compare with photo no. 18). Note the different layers (ages) of firn exposed in the small area at lower right, which can be differentiated by various shades [...]
