D. Strong 1925 (Copy) bled horses that left for parts unknown. Are all pre- pared for a hard three days in the desert passes. Spent an hour or so watching a redtail hawk being pestered by flocks of pinon jays. About twelve we started off for Cajon Canyon (Called Santa Rosa canyon by Nelson). Came across the flat thru the pines to the rim and looked out over the steep drop into the desert (San Felipe Valley) and across the gulf where the Sonoran coast was plainly visible. Dropped right over the rim -- very rough steep trail, past La Suerto, a small creek, down Los Alamosos canyon (Santa Rosa peak to the southwest) across several divides and at last into the Cajon -- much chap- paral (low prickly shrubs -- with pinyon trees down to about 6000'). F. H. Jays, Spurred Towhees Phainoepilas -- Ravens, R.T. Hawk, Vulture, and Valley Quail -- occas. to be seen. Below this the flora becomes distinctly desert like -- more cactii -- mescal, yucca, giant cactus cardon), barrel cactus, Spanish bayonet, cats-claw shrub ! Cholla, bear paw cactus, and well down about 2500' mesquite thickets along the dry stream bed occur. Here Manuel killed a brown rattlesnake which disputed the trail -- about 3' long with one rattle and a button. Down about this level, new birds appear -- the White- Winged dove especially -- this is my first sight of him. His double note coo! coo! very loud and unique.
