*According to additional information provided on 10/2011 by a member of the E.H. Davis Project Scholar Advisory Committee: This may be Obsidian Butte in Borrego near the Salton Sea. It was a source for stone tools for the Indians.
**According to additional information provided on 10/2011 by Ken Hedges, Emeritus Curator of California Collections, San Diego Museum of Man and a member of the E.H. Davis Project Scholar Advisory Committee: I agree with the previous comment on 86:15900-136 that this may be Obsidian Butte, but it is not in Borrego. Obsidian Butte, also called Obsidian Island when the level of the Salton Sea is high, is located at the southeast corner of the present sea. It was a major source of obsidian for artifacts of the Late Prehistoric period in southern California. Images 86:15900-19 and 28 appear to be the same place.
