^ CA 6. Deep Canyon and Carrizo Creek 



CC 



O Deep Canvon. Acreage: 2000 estimated. 



LL 



< 



Location: Riverside County; Palm Desert Quadrangle; 10 miles S of Palm 



O Desert; reached via Rt. 74. 



Description: Deep Canyon is a spectacular watercourse extending from the 

 coniferous forest of the Santa Rosa Mountains to the low desert of the Coachel- 

 la Valley. The lower reaches are owned by the University of California and are 

 preserved for research as the Philip L. Boyd Desert Research Center. The upper 

 reaches show marked differences in the flora and fauna with increasing altitude 

 and decreasing aridity. Moisture zones ranging from humid to arid and tempera- 

 tures from cold to hot occur within a short distance along the stream course. 



Encroachments: In order that maximum benefit may be obtained from universi- 

 ty ownership and protection of the lower reaches, it is essential that something 

 be done about the threat of private developments and sale of government lands 

 along the upper reaches of the drainage system. 



Ownership: BLM, USFS, University of California and portions by private in- 

 dividuals.

Carrizo Creek Desert Waterholes. Acreage: 10. 



Location: Riverside County; Palm Desert Quadrangle; 5 miles S of Palm Desert; 

 reached via Rt. 74. 



Description: Two permanent, small waterholes in a desert canyon. These two 

 water holes are essential to the survival of the relatively abundant bighorn sheep 

 of the surrounding area. Various other desert mammals and birds utilize the 

 waterholes. 



Encroachments: Subdivisions are getting closer and ultimately will destroy the 

 waterholes.
