THE GEOMORPHOGENY OF THE SIERRA 

 NEVADA NORTHEAST OF 

 LAKE TAHOE. 



BY 



JOHN A. EE ID 



Editor's Note. — John A. Eeid died on July 4, 1909. As a candidate 

 for the degree of doctor of philosophy in the University of California he 

 had chosen for his thesis the study of the structure of the Sierra Nevada 

 northeast of Lake Tahoe, and at the time of his death left a manuscript 

 setting forth the results of his investigations. The manuscript was nearly 

 ready for the printer, but some details were lacking ; it was his evident 

 intention to supplement it in some parts, rearrange it in others, and to 

 make some illustrative sectional drawings. I had been in consultation with 

 him during the progress of his work, and had once visited the field in his 

 company and there discussed various points with him. After his death his 

 widow sent the manuscript to me for revision, and it has been my sad 

 pleasure to perform this service for my departed friend. When the geo- 

 logical history of the Sierra Nevada is finally written, this paper of Eeid 's 

 will occupy the important place always given in science to the pioneer who 

 breaks the way to new truth. I know of no paper in recent years dealing 

 with mountain structure that shows so much ability and insight in the 

 interpretation of complicated faulting and its expression in geomorphy as 

 the one here presented. — A. C. L.
