The best places to rockhound in Central Washington are the sands and gravels of the many regional rivers and streams, as well as select mountainsides and hillsides. It remains to be seen whether future lab analyses, such as the AMS radiocarbon dating of the rock polish, the flotation of soil samples, or some future probing for ancient DNA will bring additional positive results.However, contrary to the positive results derived from the lab analyses, the field investigations have diverged from the original course. Make sure to ask the . The tremendous amount of obsidian waste material littering the sites surface suggests that it served as a workshop. SCSB-03-7: N, chalcedony end scraper.
