Township 6 South, Range 13 East. 



Topography. — The township comprises alpine and subalpine areas, mostly above 

 the 10,000-foot contour. It is rock}^ and barren thi^oughout, cut by numerous 

 creeks and canyons and dotted with lakelets and tarns. 



Mining. — None. 



Soil. — Gravelly, stony, and the surface excessively rocky and bowlder strewn. 

 Much of the tract, especially in the central areas and along the west line, has no 

 soil cover. 



Agricultural adaptability. — The township contains no tillable land. 



Grazing capacity. — All of the alpine and subalpine areas are covered with grass 

 and sedge wherever a soil cover exists, and are capable of furnishing a small 

 amount of pasturage. The tract is, however, practically inaccessible to any kind 

 of stock except sheep. 



Drainage conditions. — Lakelets, tarns, and marshy areas, with which the tract 

 is liberally supplied, act as natural reservoirs and regulate the flow of Boulder 

 and East Boulder rivers, the streams that carrj' most of the outflow from the 

 township. 



Snow and rock slides. — Common in the central areas along the canyon of East 

 Boulder River. 



Towns and settlements. — None. 



Forest conditions. — Most of the tract is situated above timber line and there- 

 fore carries no arborescent growth. Small areas of forest are situated in the 

 bottoms and on the lower slopes of East Boulder Canyon and in rayines along the 

 West line of the township. The trees are strictlj;^ a high subalpine type, of no value 

 except for fuel, and are practically inaccessible from the outside. 



Cutting. — None. 



Barns. — Along the west line of the township 600 acres have been burned over 

 in recent years and the timber totally destroyed. 



Reproduction. — Reproduction is deficient throughout the township and is scarcely 

 heavy enough to maintain the present density of stands. There is no restockage in 

 the burns. 



Undergrovjth . — Li ght.
