The roads are closed but the ANF is not air tight. I bagged the summit of Yerba Buena Ridge up from Oro Vista in Tujunga. Everything I saw from the top of that was totally burned out: From Pacoima Canyon across the whole Big Tujunga drainage, Condor, Fox, Lukens, Josephine, Strawberry.
Concerned about wildlife: I saw deer and coyote tracks. One lizard. Occasional trees and bushes. A rarely used fire road on the plateau saved that lizard and some ant hills. Found two deer, nothing left but a few bones.
I plan to continue to take advantage of the burn to access some ridges and peaks: Brown Mountain direct, Saucer Branch of Millard, direct lines on Lukens, Condor, Josephine and others.
