 108 ABSAEOKA DIVISIOJST OF YELLOWSTONE FOREST BE8ERVE. 



Snow and rock slides. — Most of the slopes in the district liaving long ^ago 

 acquired stability and a forest cover, avalanches either of snow or of rock are 

 infrequent. 



Towns and settlements. — The district has no towns. Two or three small farm- 

 steads in Rocky Fork Canyon comprise all of the settlements. 



Forest conditions. — Most of the northern slopes, where not burned over, carry 

 close-set stands of timber, 80 per cent of which is in the sapling stage and 

 represents restockage after burns thirty-five to fiftj' years ago. At the higher 

 elevations 75 per cent of this young growth is composed of white-bark pine, the 

 balance being lodgepole pine and spruce. The southern slopes have been nearly 

 deforested b}'^ fires in recent years, and carry only scattered stands of lodgepole 

 pine, mostly in the sapling stage. At the lowest elevations on all slopes lodgepole 

 pine is the prevailing species, red fir and limber pine constituting only a small 

 proportion. 



Gutting. — Small tracts bordering Rocky Fork Canyon have been cut over for 

 fencing, mine timber, and fuel. 



Burns. — Most of the southern, and some small tracts on the northern, slopes 

 have been burned over, apparently six or seven years ago. 



Reproduction. — The sapling stands are generally so fully stocked that further 

 additions are impossible. In the mature stands there is a moderate amount of 

 young growth. The recent burns are restocking scantily. Lodgepole pine 

 predominates in all of the young growth, seedling and sapling, at low and middle 

 elevations; white-bark pine prevails at the highest altitudes. 



Undergrowth. — Light. 



Litter. — There is a very great amount of dead and fallen pole timber, both 

 in the green and in the burned stands. The accumulations are constantly increasing 

 by further downfalls of the fire-killed trees. 



Humus. — None.
