 the old or mature growth.

Township 7 South, Bange 15 East. 



The township comprises a high, mostly alpine region, abounding with crags, 

 precipices, and bare rocky peaks rising to altitudes of 12,600 feet, and deep, cliff- 

 bound canyons. None of the areas are agricultural; none have a grazing value; 

 none are forested; scattered trees of subalpine species grow here and there in the 

 lower and more sheltered ravines, but as most of the region is situated above 

 timber line, there never can be any extensions of the present amount of arborescent
