(Abandoned road, as the ranch north of here at mouth of canyon down at La Tuna Canyon burned down a long time ago.) We went down into a small draw northeast of saddle, then came back up another canyon to the east of the main fire road on the crest of the ridge (Verdugo Motorway). Basically a triangle.
