Township 7 South, Range 14 East. 



Topography. — The eastern and western areas comprise steep, rocky spurs 

 rising to elevations of 10,000 to 11,000 feet. The central areas consist of the 

 canyon of Stillwater River and its immediate slopes. The canyon is a rocky 

 gorge hemmed in by steep slopes, which in the southeast portion become immense, 

 towering cliffs rising sheer from the valley 2,000 to 2,500 feet. 



Mining. — None. 



Soil. — Gravelly and stony, with light surface admixtures of loamy matter. 



Agricultural adaptability. — None of the areas are tillable. 



Grazmg capacity. — The summits of the spurs are covered with a thin sward 

 of alpine and subalpine sedge and grass. The eastern areas are practically inac- 

 cessible. The western areas can be reached, but probably only hy sheep. 



Drainage conditions. — The tract gives rise to numerous springs and creeks, 

 but owing to the broken character of the region holds no lakelets. 



SnMj} and rock slides.— Yevy frequent along the canyon of the Stillwater, 

 owing to the excessively steep slopes. 



Towns and settlements. — There are no settlements in the township. 



Forest conditions. — The timber is confined to the canyon of Stillwater River 

 its larger western tributaries, and a few of the lower and less rocky slopes. 

 The stands are composed of lodgepole pine in nearly pure growths or with large 

 proportions of spruce and subalpine fir, and vary in age from 60 to 200 years, 

 depending on the time that has elapsed since the last firev The forest is prac- 

 tically inaccessible, except for local use.
