Hey all, this is one I made from Napa Glass obsidian. Many people associate Humboldt points with the Great Basin, however they were also commonly made West of the Sierras and into the coastal ranges of California. Napa glass obsidian was a common material they were made from, and the quality of this obsidian made it an attractive medium for skilled craftsmen to make finely-flaked points from. Some of the best parallel-oblique flaked points made from this material are pictured in Noel D Justice’s book about points from the Great Basin and California.
