GLACIAL PHENOMENA IN NEVADA 



action of the ice. Its height is approximately 

 eleven thousand three hundred feet above the 

 sea. 



A few days after making these interesting 

 discoveries, I found other well-preserved gla- 

 cial traces on Arc Dome, the culminating sum- 

 mit of the Toyabe Range. On its northeastern 

 slopes there are two small glacier lakes, and 

 the basins of two others which have recently 

 been filled with down-washed detritus. One 

 small residual glacier lingered until quite re- 

 cently beneath the coolest shadows of the 

 dome, the moraines and nv-fountains of 

 which are still as fresh and unwasted as many 

 of those lying at the same elevation on the 

 Sierra ten thousand feet while older and 

 more wasted specimens may be traced on all 

 the adjacent mountains. The sculpture, too, 

 of all the ridges and summits of this section 

 of the range is recognized at once as glacial, 

 some of the larger characters being still easily 

 readable from the plains at a distance of fif- 

 teen or twenty miles. 



The Hot Creek Mountains, lying to the 

 east of the Toquima and Monito ranges, 

 reach the culminating point on a deeply ser- 

 rate ridge at a height of ten thousand feet 

 above the sea. This ridge is found to be made 

 up of a series of imposing towers and pinnacles
