Type locality, Trout Lake, Cascade Mountains, Washington. 



The Cascade Mountain Fox is found in the Cascade Moun- 

 tains of Washington and Oregon and in the northern Sierra Ne- 

 vada. This species and the High Sierra Fox belong to the group 

 which in one pelage is called the Silver Gray Fox and in another 

 pelage the Cross Fox. The latter name is due tO' the fact that a 

 dark stripe on the top of the neck and back is crossed by, another 

 on the shoulders. The Silver Gray Fox is black with the hairs, 

 particularly on the hips, with long white tips, producing a silvered 

 appearance. This stage of pelage is probably very rare in Cali- 

 fornia, if it really occurs at all. These different pelages are not 

 seasonal but are to a considerable extent dimorphic, though there 

 is also some seasonal differences.
