Havallah Range. — This range, situated to the westward of the Fish 

 Creek and Battle Mountain groups, is connected with the former by a nar- 

 row outburst of rhyolite, and with the latter by a low obscure ridge, 

 apparently made up of Palaeozoic strata. The range extends southward 

 from the Humboldt River, a few outlying hills, however, appearing on the 

 northern side, for over 60 miles, where it falls away in a long low point 

 of volcanic rocks, running out toward the depression known as Osobb Valley. 

 The southern portion forms a narrow singlie ridge along a nearly north and 

 south line until opposite the lower end of the Battle Mountains, where it 

 bifurcates, the main uplift extending to the northwest, while the lesser one 

 trends a few degrees east of north, the two being separated by a high 

 Quaternary valley 3 or 4 miles in width. Across its narrowest portion, the 

 range, although having a high elevation, scarcely measures 5 miles in width, 

 while its broadest expanse reaches, including the intervening valley, nearly 

 22 miles. 



Signal Peak, at the northern end, is the culminating point of the 

 range, attaining an elevation of 9,387 feet above sea-level. It stands out 

 prominently above the surrounding country, and affords, from its summit, 

 one of the most commanding views in all directions to be found in this 

 portion of Nevada. Westward the view extends through a low gap in the 

 Montezuma Range, across the Mud Lake Desert, to California ; eastward, 

 across the Shoshone Mesa, and up the valley of the Humboldt River; and 

 southward to the extreme end of Osobb Valley. 



Southward from Signal Peak, the ridge falls off gradually to Bardmass 



Pass, below which it gently rises, and, where the east and west uplifts 



come together, forms a bold mountain mass as far as Tobin Peak, just 



north of Grolconda Pass. In comparison with most Western Nevada ranges,
