TOWNSHIP DES0BIPTI0N8. 



121 



Dramage condn,tions. — The region is dotted with a large number of lakes and 

 tarns, all of great importance as constituting a series of natural reservoirs for Clark 

 Fork. The run-off is steady and of considerable volume. 



Snow and rock slides. — Not infrequent in the high and precipitous northern areas. 



Tovms and settlements. — The township is not inhabited. 



Forest conditions. — The southern and central areas are covered with fairly uni- 

 form old-growth stands of lodgepole pine and Engelmann spruce. The northern 

 areas bear thin stands of white-bark pine and spruce, or are wholly without forest 

 cover. The timber in the southern and central areas is comparatively easy of access. 



Cutting. — None. 



Burns. — None. 



Reproduction. — Good and abundant, except in the high northern areas. The 

 prevailing species in the sapling and seedling growth is lodgepole pine, followed by 

 Engelmann spruce. 



Undergrowth. — ^The underbrush is sparse and scattering, particularly in the 

 pure-growth lodgepole-pine stands, or where this species predominates. 



Litter. — Abundant along the streams and margins of tarns, and in general 

 where seepage prevails. It consists largely of spruce uprooted and overthrown by 

 wind. 



Humus. — There is commonly a thin layer of moss and decaying pine needles in 

 the close-set stands,' especially where the ground is swampy. In the more open 

 forest on the uplands and at subalpine elevations the humus is lacking.
