THE POST-PLEISTOCENE ELEVATION OF THE INYO 

 RANGE, AND THE LAKE BEDS OF WAUCOBI 

 EMBAYMENT, INYO COUNTY, CALIFORNIA. 



The following notes are the result of observations made in 

 the summers of 1894 and 1896. My routes were : first, from 

 Alvord Station on the Carson and Colorado Railroad eastward on 

 the Saline Valley road, passing through Waucobi Canyon and 

 over the divide seventeen miles E. S. E. of Alvord ; second, from 

 Alvord through Soldier Canyon, over the range to Deep Spring 

 Valley. 



As seen from the foothills of the Sierra Nevada, looking 

 across Owens Valley, the axis of the low portion of the Inyo- 

 White Mountain Range, between Soldier Canyon and the ridge 

 south of Waucobi Canyon, arches strongly to the eastward, and 

 forms a broad embayment between Soldier Canyon on the north 

 and the head of Waucobi Canyon on the south. (Fig. i.) The 

 range from east of the divide at the head of Owens Valley to 

 Owens Lake is practically one, but unfortunately it has been 

 given the name of White Mountain to the north and of Inyo 

 Range ^ to the south of the embayment. Inyo is here used to 

 include the range south of Soldier Canyon. For the broad 

 embayment formed I use the name Waucobi, and for the ancient 

 lake in which the lake beds were deposited the name Waucobi 

 is also adopted. It was the examination of the lake beds 

 deposited in Waucobi embayment that led me to conclude, from 

 their position, that a marked orographic movement had taken 

 place in the Inyo Range since Pleistocene time. 



In crossing Owens Valley, from Alvord Station eastward, 

 the lake beds are met with about a mile and a half east of the 

 station, at an elevation of 100 feet above the railroad track.
