Clear Lake Calif. Blade - Indian Arrowhead, artifact

This is one of a large number of arrowheads and artifacts that I will be selling in the next few weeks from my collection. This obsidian blade was found at Clear Lake, Lake County California. It was found when the lake receded during a drought in the 80's, and the obsidian surface has been dulled by the immersion. The blade is 3 1/8" long. Sold with no reserve.
