BROADLEAVED TREES OF YOSEMITE NATIONAL PARK 



17 



upper altitudinal limits of its range 

 it assumes a scrubby character. 



The canyon hve oak is found be- 

 tween the 3,000 and 6,000 foot eleva- 

 tions. It thrives in protected canyon 

 bottoms, a fact responsible for its 

 common name, and has a particular 

 affinity for the talus slopes and rock 

 slides bordering such places. It is 

 one of the most abundant trees in 

 those places about Yosemite Valley 

 and will be readily found along the 

 lower parts of trails leading from the 

 Valley floor to the rim — as in the case 

 of the Yosemite Falls trail, the Four 

 Mile Trail to Glaciar Point, about 

 Happy Isles, and along tV^e trail from 

 that point to Nevada Fall. 



It is a slow growing but fairly long 

 lived tree. Mature specimens attain 

 an age of from 200 to 300 years.
