Chinookan worked Rocks?

[USNFLYR]

Hello all,

I found some stones that appear to be of different types of material with varying signs of wear.

The first is basaltic. A clear dimple exists. On the back side it looks like an area would’ve displayed a "worked" dimple but the outer shell broke off. Could this be a nutting bowl or an arrowhead making stone? If was found in an area that had salmon fishing and camping from lower Columbia River tribes.





Second stone is shaped like a tool. Axe head, club or weapon? Chips on leading edge. I am not sure if the native people used clubs affixed to wooden handles so this might be a stretch.







Please chime in....been looking all COVID season for "keepers"....but as of yet the garden has collected many rivers stones with interesting dimples!

The first one with the large divot is most likely an Anvil Stone used in the flaking process of Flint Tools as a base. Or so I've read

First one appears to be what we call a nutting stone. While they may have been occasionally used for nyrs ,They are actually multi purpose anvil . flaking point's grinding edges, grinding grain, etc.

The second item doesn't show obvious sign of alteration unless the bit us ground out. It does appear to have use damage though but I can't be sure. Cool items
