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. These collections are around the bend in the canyon. The canyon is narrower here and thick with brush, as the canyon is not very incised into the mountains. 550 Comment
