in the aggregate to 2,000 acres. Most of the central areas, about 10,000 acres, 

 were burned over sixty or seventy years ago. 



Repro&uction. — There is a moderate amount of young growth throughout the 

 central portions, but nowhere is the restockage at all dense. The grassy fire 

 glades that came into existence sixty or . seventy years ago show a tendency to 

 become permanent. Some of them are covered with dense- brush growths in which 

 the seeds of coniferous trees obtain lodgement with extreme difficulty. Lodgepole 

 pine prevails as young growth at all the lower altitudes. Seedling and sapling 

 growth are scanty in the subalpine forest. 



Undergrowth. — ^There is little brush growth in the subalpine forest or in the 

 well-stocked stands of lodgepole pine at the lower elevations. Dense brush covers 

 many of the old fire glades. It is composed of Shepherdia, Canadensis, Oea/notlms 

 velutinus, juneberry, wild rose and the like. 



Litter. — In the lodgepole pine stands the amount of litter is small. In the 

 subalpine forest, particularly where Engelmann spruce is abundant, there is an 

 immense amount of uprooted timber, due to heavy winds and to the springy 

 character of the ground. 



Humus. — In the spruce stands on the east side of the valley the humus or duff, 

 composed of moss, is 3 to 6 inches in depth. Elsewhere in the township it is lacking.
