6olden Trout of Mount Whitney 



tant of small mountain streams on the western slopes of Mount 

 Whitney, tributary to Kern River. It is locally abundant in Vol- 

 cano Creek and the South Fork of Kern River. It has also been 

 introduced into streams about Owen Lake, on the east slopes of 

 the Sierras, which were formerly without trout. The golden 

 trout has been derived apparently from the Kern River trout. 

 It is a small trout, reaching a length of only a few inches, and 

 is remarkable for its unexcelled gameness and its unsurpassed 

 beauty.
