      I’d say basalt too, of which there are many many types. The NA people loved it to make their tools, of all kinds...

          Thanks, everybody.

          Now I'm confident it's basalt.

            Looks like basalt. The basalt from the Northern CA Lassen country up into Modoc and southern Oregon is more grayish/Black with a flat sheen. Like the looks of that stuff. Cool find
