Some five approached to about 20', to take photo, the cat ran out, up the rocks & away. | Both squirrels - on or off 5' level on rocky slope! (crossing to S. bank immediately) We departed for Mesteros. Road wound around hills, sometimes rocky, with much ocotillo, & other tumer dry grass. Occasional gates. | About 11 mi.

S. of S.L., road broke farther to E. of canyon and higher into the hills, so more grass & less ocotillo. When boulders + ocotillo, no greenery, I saw 2 Bob-Cats. | About 15 mi. S., oaks and junipers, + about 19 mi. S., dry grassland hills with live oaks to 30' high, 1/2 drain along draws. There saw black-headed Grosbeaks, a few Woodpeckers, W.
