township descriptions. 85 



To-w;nship 7 South, Range 13 East. 



Topography. — This township is a plateau-like area situated mostly above timber 

 line, cut by shallow canyons and dotted with numerous tarns. 



Mining. — None. 



Soil. — Thin gravelly loam. 



Agricultural adaptaMUty. — The township contains no tillable land. 



Ch'asing capacity. — Most of the township is covered with a thin sward of alpine 

 grasses and sedges which might afford a scanty pasturage during three or four 

 months of each year. 



Drainage conditions. — Owing to its elevated position the region receives a large 

 amount of snow and rain, and the run-off is large. The tract abounds in tarns, 

 springs, and creeks, and constitutes an important water head of Boulder and Still- 

 water rivers. 



Snow and rock slides. — Infrequent. 



Towns and settlements. — None. 



Forest conditions. — The forest is of subalpine composition throughout, and 

 consists of white- bark pine, spruce, and subalpine fir, with lodgepole pine in the 

 southwest corner. On a small tract in this corner, the forest is set in a close, 

 well-stocked stand; elsewhere the stands are thin, and scattered over the rough 

 surface and slopes in nai'row lines and small copses. It is chiefly an old and middle- 

 aged growth. Except for local use the forest is inaccessible. 



(Jutting. — None. 



Burns. — ^ Along the west line of the township the timber on 1,200 acres has been 

 killed by recent fires. 



Reproduction. — Scanty throughout. The young growth is composed of the 

 same species, in the same proportions as the mature forest. 



Undergrowth. — There is only a very low and thin growth of underbrush in 

 the district. 



Litter. — Abundant in the southwest comer of the township, consisting of 

 dead and fallen pole growths, killed by overcrowding. 



HuTTius. — Thin or entirely lacking.
