The top two are early ones, both end scrapers. (?) Cant tell if the top right one is broke or flaked that way from the shadow on the pic. Anyway, you got probably a Cache Creek end scraper, and a Meserve end scraper there. The two in the middle are knives, the red one is prolly Gary related. The dark one, its hard to tell, but looks possibly paleo re work? Intresting peice there. The bottem is a flake knife. A lot of those date back also from paleo times as well. Matt Rowe could tell you WAY more about it than anyone here. (Neanderthal)
