90 ABSAEOKA DIVISION OF YELLOWSTONE FOREST RESERVE. 



Drainage conditions. — The run-off is large and continuous, and as the tract 

 serves as a natural reservoir for the two Rosebud creeks it is of great importance. 



V Snoiu amdrock slides. — These are common, especially in East Rosebud Canyon. 

 Enormous masses of overhang line the brinks of the canyons and frequently send 

 down vast masses of rock and gravelly debris. 



Towns and settlements. — There are no towns on the tract. At the north end of 

 East Rosebud Lake, a sheet of water covering Y50 acres in the canyon of the same 

 name, is a summer cottage belonging to a Major Armstrong, who occupies a tract of 

 surveyed land in the heart of the mountains far from all other surveys. 



Forest conditions. — The forest consists of thin stands of lodgepole pine, red fir, 

 white-bark pine, and spruce in the canyons and on the declivities where the slope 

 is not too steep to permit soil to accumulate. Small stands of aspen and cottonwood 

 occur in the bottoms of East Rosebud Canyon, while a few copses of yellow pine 

 occupy tracts at the mouth of the canyon. Forrnerly the bottoms and slopes of 

 East Rosebud Canyon were closely stocked with timber in most places, out very 

 little has escaped the fires during the last four or five years. 



Cutting. — Small quantities here and there for local use. 



Burns. — During the past six or seven years most of the township has been 

 burned over. Complete destruction of the timber has followed. 



Reproduction. — There is little young growth. The burned tracts show practi- 

 cally no evidence of reforestation. Especially is such the case on the southern and 

 western exposures. Since the fires many of the slopes show extensive gullying, 

 while on most of them the loamy surface is being washed into the streams and 

 carried away, a process which will indefinitely retard reforestation. 



Undergrowth. — Moderate in quantity. A few of the burns are growing up to 

 various sorts of brush, mostly Ceanothus. 



Litter. — There are large quantities of dead and fallen timber on the burned-over 

 tracts. Most of the dead timber is still standing, and when it falls the amount of 

 litter will be very large. 



Humus. — None.
