These are three of the most common material types in my part of Northern California. Obsidian, no news there, basalt and chert. The chert wasn’t as widely used for chipped items as obsidian but I’ve found a good amount of scrapers and choppers as well as a few points and other pieces. Some shown are barely worked while others weren’t worked at all. The basalt items shown are some broken pestles. Of note is the porous type my grandpa used to call ‘lava rock’. The obsidian shown is most likely a cross section of types from the two and possibly a third main glass sites. The scraper is a banded type. Hopefully pics are visible.
