342 NOllTH AMERICAN FAUNA. [No. 7. 



Pahranagat Mountains. — Common on the summit of the range, reach- 

 ing* down to 1,585 meters (5,200 feet) on the east slope. 



Paliroc Mountains. — Common on the higher parts of the range and in 

 canons. 



Hyl;o Range. — Common on the higher parts. 



Highland Range. — Abundant, descending to about 1,830 meters (G,000 

 feet) on the west side. On the east side of the Highland Range it de- 

 scends to 1,700 meters (5,000 feet), thus reaching within a few hundred 

 feet of the bottom of Meadow Creek Valley. 



Juniper Mountains (between Meadow Creek Valley, Nevada, and 

 Shoal Creek, Utah). — The most extensive and purest juniper forest I 

 have ever seen covers the rolling plateau along the boundary between 

 Nevada and Utah, reaching from an altitude of 1,765 meters (about 

 5,800 feet) on the east side of Meadow Creek Valley, Nevada, all the 

 way across to Shoal Creek on the borders of the Escalante Desert in 

 Utah. This continuous juniper forest is more than 20 miles in breadth 

 without a break and is mixed with very little nut pine. On the Shoal 

 Creek side it descends to 1,830 meters (G,000 feet). The altitude of the 

 plateau which it occupies, and which is here called the Juniper Moun- 

 tains for lack of a better name, varies from a little over 1,830 meters 

 (6,000 feet) up to about 2,100 meters (7,000 feet). 



Charleston Mountains. — Common throughout the Charleston Moun- 

 tains, excex>t on the summit of the main peak, which is too high for it. 

 On the w T est slope (Pahrump Valley side) it descends to 1,550 meters 

 (5,100 feet). 



ARIZONA AND UTAH. 



Virgin and Beaverdam mountains. — Common in a broad zone on the 

 Virgin Mountains, reaching down more than halfway to the valley; 

 and on the west slope of the Beaverdam Mountains down to 1,340 

 meters (4,400 feet). 



UTAH. 



Beaverdam Mountains. — On the east slope junipers descend to 1,095 

 meters (3,600 feet) spreading out to the northward over the upper part 

 of the Upper Santa Clara Valley, where they cover all the sidehills. 



Pine Valley Mountain. — Abundant in a broad zone around the base 

 of the mountain, and stretching thence northwesterly over the Upper 

 Santa Clara Valley, forming a sparse forest on the hillsides until it 

 reaches the Shoal Creek country, where it joins the continuous forest 

 already described. In the Upper Santa Clara Valley it descends 

 to 1,280 meters (about 4,200 feet) at a distance of only 13 kilometers 

 (8 miles) northwest of St. George, thence forming a scattered forest 

 over the sidehills in a belt at least 10 miles wide south of the Upper 

 Santa Clara crossing, and reaching thence northerly to the borders of 

 the Escalante Desert, south of which it is continuous with the great 

 forest covering the Juniper Plateau.
