 NEMESIS MOUNTAIN 



From Monida, proceed east on the main Centennial Valley gravel road 44.5 miles to Red Rock Pass 

 and park. Take the Continental Divide Trail 1.5 miles south the the northern edge of the site. 



Nemesis Mountain is a prominent metamorphic rock peak with 2700 feet of relief relative to the 

 Alaska Basin directly to the north. The upper elevations of the mountain are characterized by 

 extensive areas of scree and Pinus albicaul is-Abies lasiocarpa communities. Within the scree 

 and forested scree sites, patches of a state rare plant, Lesquerella (paysonii or prostrata), 

 are present. 



COUNTY: Beaverhead 



uses QUADRANGLE: MOUNT JEFFERSON 



TOWNSHIP-RANGE: OUSOOIE SECTION: 25 



QUARTER/ADDITIONAL SECTIONS: Portions of 25 and 36 in TUSR1E, and 30 and 31 in TUSR2E. 



BOUNDING RECTANGLE: S: 443406N N: 443513N E: 1113130W W: 1113313W 



BOUNDARY JUSTIFICATION: The primary boundary generally follows the 8000-foot contour around Nemesis 

 Mountain. This boundary contains all the known Lesquerella sites on Nemesis 

 Mountain. 



APPROXIMATE ACREAGE: 700.00 



GENERAL RATING: 2 



An SI plant species is present (Lesquerella paysonii or Lesquerella prostrata). 



BIODIVERSITY SIGNIFICANCE: B3 



Large populations of an SI plant species are present. Populations were observed on ridges and 

 upper slopes with open Pinus albicaulis-Abies lasiocarpa forests southeast of Nemesis Mountain 

 and on a scree-covered avalanche chute to the northeast of the mountain. 



OTHER VALUES: V2 



Nemesis Mountain is a prominent and highly aesthetic feature of the landscape. 



PROTECTION URGENCY: P4 



The slopes are too rocky and steep for most domestic stock and it is doubtful the site is 

 threatened by anthropogenic disturbance. Consider establishment of a Nemesis Mountain ACEC. 



MANAGEMENT URGENCY: M4 



Carefully regulate use by sheep or other stock capable of grazing the steep and rocky country 

 which characterizes the site. 



CONSERVATION INTENT: Recommend establishment of a BLM ACEC. 



PROTECTION COMMENTS: Most of the Nemesis Mountain site is by coincidence protected from timber 

 harvest and most livestock use by very steep and rocky slopes. 



LAND USE: The steep rocky slopes of this site have been, and are now, primarily used for wildlife habitat 

 and watershed values. 



NATURAL HAZARDS: Numerous cliffs, steep rocky scree, snow avalanches, and severe electrical storms 

 constitute hazards. 



EXOTICS: None observed. 



OFF-SITE LAND USES: 



INFORMATION NEEDS: Identify and describe the full range of community types present on the site. 

 More thoroughly survey the site for occurrences of rare Lesquerella species. 



MANAGEMENT NEEDS: Designate a Nemesis Mountain ACEC focusing on protection of Lesquerella paysonii 

 or L. prostrata and pristine subalpine vegetation.
