INTRODUCTION. 



Mineral King is situated on the headwaters of the East Fork 

 of the Kaweah River near the western crest of the southern 

 Sierra Nevada. This portion of the range is known as the High 

 Sierra, and is preeminently distinguished by the sharply serrate 

 character of its profiles and the vast assemblage of lofty peaks.
