I was watching a video and the guy on it was in Oregon in the glass butte area. It was nuts how much obsidian was just laying on the ground. I started looking for info about it and it’s crazy how much obsidian is there. Every color you can think of, you name it and it seems to be there. My daughter went to grad school in Oregon and I was there a 3-4 years ago. We went to crater lake and on down into Northern California to Jedidiah Smith redwood forest outside of crescent city. If I had of been doing the knapping thing then and know what I do now I definitely would have made a stop by there. Love to take a trip there someday.
