I was hiking in a nearby creek area. While climbing the bank, I found this scraper. Not really a knockout but it was a nice surprise. Along the sandstone banks there are several bowl like impressions in the rock. I suspect that these were used by the women to leech the tanins out of the acorn meal- that was a large part of their diet.
In ancient times in our area, the Yuki tribe was here. They hadn't the trade connections to gain access to the obsidian deposits 30 miles SE into enemy Pomo territory. The Pomo people would eventually push the Yukis out to the north- where they resided until European contact.
The Yukis used a stone called Franciscan Chert. It is more like flint and found among basalt deposits.It's closer to flint than obsidian, which is like volcanic glass. It is often brown, but can be green, white or even blue.
