FOREST. 



The forested areas comprise only § per cent of the quadrangle, and are con- 

 fined to the southwest corner. They lie almost wholly within the limits of Yellow- 

 stone Forest Reserve in T. 2 S., R. 14 E.; T. 3 S., Rs. 14 and 15 E.; T. 4 S., 

 Rs. 14 and 15 E. Where not devastated b}'^ fire, they carry well-stocked stands of 

 red fir, limber pine, and lodgepole pine, with small proportions of Engelmann 

 spruce in the canyons and on the northern slopes. The red fir is the dominant 

 species, forming 66 per cent of the stands, followed by lodgepole pine with 4(i 

 per cent, while limber pine adds soiuewhat less than 5 per cent. The timber is 

 extremely difficult of access, owing to the broken character of the ground where 

 it grows. Most of the timber is either a pole growth or else so short, stocky, 

 and knotty that it is unfit for mill timber. Fully 85 per cent is only valuable 

 for pole and fuel timber. The total volume of timber in the quadrangle is shown 

 in the subjoined table.

The forested area has been cut over in the upper Deer Creek drainage on 

 areas aggregating 200 or 300 acres. The woodlands have been culled in most of 

 the accessible places, the cut amounting to less than 5 per cent.
