CANADIAN ZONE. 



The Canadian zone on Sbasta forms a broad forest belt, usually sev 

 eral miles in width and about 2,000 feet in vertical depth, which com 

 pletely encircles the mountain. On southwesterly slopes it begins at 

 an altitude of about 5,000 to 5,500 feet and pushes up to 7,r)00 to 7,800 

 feet. 



Excepting" an area of lodge-pole i)ines [rinus murrayana) on the 

 northeast base of the mountain, the Canadian zone is everywhere 

 marked by a continuous forest of stately trees, consisting of Shasta firs 

 {Ahies shastensis)y mixed in places with silver pines {Pimis monticola). 

 It is a dark, somber forest, growing on a blackish soil, with very little 

 noticeable vegetation except scattered patches of dwarf nianzanita in 

 the dry woods, and lines of more succulent plants at widely distant 

 intervals along the borders of streams.
