56 ABSAEOKA DIVISION OF YELLOWSTONE POEEST EESEEVE. 



in West Boulder Valley is -accessible for logging, although with some difficulty 

 owing to the bowlder-strewn condition of the valley bottom. The timber on the 

 slopes is inaccessible. West Boulder Eiver can probably be utilized for driving 

 purposes early in the season. 



Cutting. — None. 



^wms.— Scattered patches of forest here and there in the valley of West Boul- 

 der have been damaged by fires of recent date. 



Reproduction. — At the lower elevations there is enough young growth to 

 maintain the present average density of the stands. In the higher subalpine^ areas 

 the reproductive capacity of the forest is low, and the trees show little tendency 

 toward spreading into the various grassy, nontimbered glades that break the con- 

 tinuity of the stands. 



Undergrowth. — The bottoms of the West Boulder and its larger laterals bear 

 thick and tangled masses of willows, alders, etc. There is little brush growth in 

 the stands on the ridges. 



Litter. — The forest in West Boulder Valley is littered with large quantities 

 of dead and fallen timber. Elsewhere in the township the litter is light. 



Humus. — The forest floor on the western slopes of West Boulder Valley is cov- 

 ered with a 3 to 4 inch layer of moss^and pine needles. In the subalpine stands 

 humus is very light or mostly lacking.
