growth. Roches moutonnées occur at many points above 11,000 
feet. Near the pass into the valley of Mineral Creek, at an eleva- 
tion of 11,900 feet, striae on rock in place bear N. 47° W. Some 
lakes in rock basins occur, the largest being at 11,600 feet (Fig. 
5). Near the margin of the valley the usual talus slopes are found, 
some of which have weathered until they support sufficient vegeta- 
tion to give the slopes a covering of green; but for the most part 
Fic. 6.—Part of the divide between cirque at head of Trout Lake branch of Lake 
Fork (on the right), and valley of Cascade Creek (on the left). Elevation of gap 
in lower central part of view, 12,700 feet. The surface of the glacial ice in the two 
cirques is believed to have been about up to the lower part of the gap. 
the débris consists of apparently unweathered fragments. Fig. 6 
shows the steep walls of a part of the southern boundary of the 
valley. 
The eastern slope of the valley, including the tributary valleys 
from Poverty Gulch to the cirque-valley just above the village of 
San Bernardo, is steep, irregular in topography, and mostly 
covered with forest. Roches moutonnées occur at a few points, as in
