And of course, you're correct on the obsidian. I think there's three sources on the east side for most all of the Native American artifacts found in the Sierra. Heavy trading with the west side Indians. There are trading sites near some of the major passes with thousands of pieces left when the larger blocks were broken of up to make blanks to be later used for points.
George - You mention three sources for obsidian. If one is Glass Mountain - I'm aware of a second in the Coso Range. Where's the third?
