Verdugo Mountains North side of Verdugo Mountains. South of Hostetter Motorway (in Thomas Guide) just off La Tuna Canyon Road, south of and you can see the 210 Freeway. Unnamed canyon that Hostetter road follows to near the main crest. Could be La Tuna Canyon as this is near the head of that canyon. If this is La Tuna Canyon, then the canyon makes a turn from draining to the west, turns south so the drainage is north. Around the bend in the canyon near above coordinates.
