Ever Canyon & Cold Canyon, San Gabriel Mountains, Los Angeles Ca.,
California. Elevations: Ever Canyon 2500 ft Cold Canyon 1800 ft.
April 7 After I returned Jim deLauriers to his office at Clapper College,
I drove at his suggestion to Ever Canyon, off 224 Baldy Road 1/2 mile N. of San Antonio Dam on San Antonio Creek, just inside Los Angeles County's eastern border. This is a pretty, oak dominated canyon (Q. chrysolepis mostly) with toyon shrub understory and a small
forn in the creek. The canyon drains ESE to San Antonio Creek. I visited only briefly (14:00 to 14:45), walking swiftly up canyon to judge greorgia population size. They did not appear to be numerous.
I then drove (again at Jim's suggestion) to Pomona College to meet someone who might steer me to a good field site. He was not avail-
able, but Rachel Zarin, a new biology faculty person there, suggested Cold Canyon, due N. of Campus at the end of Miles Avenue. Cold Canyon drains SE, with little flow in the creek. Cold Canyon vegetation was again dominated by oaks and toyon, but the plants seemed much smaller than individuals in Ever Canyon. In spots along the creek there were a few willows and a few alders. Adenostoma chrysophyll covered the lower I medium elevation slopes, which were much more visible here than at Ever C. There were pockets of eucalyptus and oaks, visible at a distance high in the canyon. I visited Cold Canyon from 16:45 to 17:00 (approx).
Birdsrikes were numerous at Cold Canyon.
Weather: this afternoon was clear, with a fair 5-10 mph W. wind.
Temperature about 70°F, down slightly at sundown.
