NOTES ON THE, GEOLOGY OF EASTERN 
CALIFORNIA.

Introduction. 
The region which forms the subject of the following geo¬ 
logical sketch lies east of the Sierra Nevadas, south of Mono 
lake, and north of the Mojave desert. It includes a stretch 
of country nearly 200 miles long and 75 miles wide. Much 
of it possesses a desert and forbidding character. Partly on 
that account and partly because of its remoteness no geologi¬ 
cal work of more than reconnaissance character has ever been 
undertaken. A short description of the region about Owen’s 
and Death valleys is given by Whitney.* Parties belonging 
to Wheeler’s survey crossed it at different times and some 
brief notes have been published by Gilbert, f W. A. Good¬ 
year while connected with Whitney’s survey traversed the 
Inyo and White Mountain ranges.]; In the summer of 1894 
C. D. Walcott made a brief examination of the White Moun¬ 
tain range.§ The writer spent nearly five months of the 
spring and summer of 1895 in the region and made the obser¬ 
vations which form the basis of the present article.
