Oh lol! That looks like a Western Stemmed point! That’s the precursoriest projectile point to have chosen.

For ages the model of the Peopling of the Americas was Clovis First - that the people associated with the beautiful fluted Clovis Point tradition were the first through the ice-free corridor. But these Western Stemmed Points kept turning up very early in the PNW and they look like much older points from eastern eurasia. Clovis first was gospel though, so no-one was willing to accept the existence of a clovis precursor, even though these are what, when and where we’d expect a pre-Clovis stone tool tradition to look like.

Nowadays some kind of small pre-clovis presence is widely accepted. So these were quite controversially precursors.
