INTRODUCTION. 



During the past season the Sierra Club held its annual outing 

 in the basin of the Upper Kern River. In the large party of 

 enthusiastic mountaineers who participated in the excursion were 

 two geologists. One of these was Mr. G. K. Gilbert and the 

 other was the writer of this paper. Both were attracted by the 

 opportunities which were afforded by the Club's program for 

 exploring, from a geological point of view, this little known but 

 highly interesting portion of the Sierra Nevada, and at the same 

 time indulging in a few weeks of exhilarating recreation. 



The observations, upon which the present sketch of some of 

 the geological features of the region is based, were made to a 

 large extent by both Mr. Gilbert and the writer while travelling 

 together over the mountain trails and climbing the peaks that 

 served as vantage points, from which we looked down upon and 

 viewed, as a map spread at our feet, the country through which 

 we passed. The interpretation of these observations was a com- 

 mon theme of conversation both at the time they were made and 

 in cam]). Under these circumstances it is evident that a large 

 share of whatever merit this sketch possesses belongs to Mr. 

 Gilbert. In so far as it is desirable that the common observa- 

 tions should be made a matter of record, it would have been 

 better for geological science had the writing of this paper been 

 undertaken by Mr. Gilbert; but he, pleading pressure of more 

 important work, has generously waived the rights of authorship
