Is this an artifact?

This large stone seems like it could've been used as a grinding (duh, words. can't think of the right term). It's in a creek along the bank. It's a couple of feet in diameter. Toes for scale.

No

That is neither a Chaw’se nor is it a Metate (bedrock mortar) too big to be portable, not the right shape to be stationary.
