Not illustrated. 1907 Excerpt: ...Creek, in which the ice moved almost directly north to the main valley. At the lower end of this cirque the valley walls are glaciated only one-third of the way up the slope, so the valley could never have been nearly full of ice. Below the upper limit of the ice the ends of the spurs from the Mount Elbert ridge have been truncated and the valley is U-shaped. The walls of this valley, even where it has been glaciated, are weathered considerably, so that none of the original glaciated surfaces remains. The rock surface is everywhere covered with talus, and the shape of the valley gives fhe only clue to the height reached by the ice. Near the head of Elbert Creek the valley is somewhat broader and the head walls rise in a steep, unbroken slope to the crest of the ridge. This head wall is covered with talus, and the upper limit of the ice could be determined at points only. The west wall of the cirque is broken into a number of minor valleys, and the upper limit of the ice is an irregular line much obscured by talus, but determinable at many points by rounded shoulders or truncated spurs. At the lower end of this cirque, as of heads 1 and 2, there is a drift plug in the valley. It dams up the mouth of the cirque to a considerable height, and the stream has a steep gradient on the outside of this plug. MAIN VALLEY. The main valley, below the junction of these three heads, has a broad U shape, but is not altogether free from loose material. Even in the light-drift area there is considerable drift in patches. On the north valley wall the upper limit of glaciation is very indistinct. On the south wall the glaciation was more intense and the ice was higher than on the north side. This may have been caused by the north wall receiving more heat from the sun and thus ...
