Surprise

All of the photos are the same piece, from different angles.

My guess (based on decades of collecting points in Oregon) is an aborted point that was tossed and has since seen lots of time, weather and abuse. There seem (to me) to be breaks that were not part of the work.

This find was particularly surprising to me because while it's been documented that there were humans in this area upwards of 10,000 years ago and many artifacts have been found within 20-100 miles of where it was found, I've never heard of any being found specifially where I found this one.

I would say a lot longer than 10,000 years for people to be in that area. There is an excellent thread somewhere here about human migration. Think it is under the articles section. Written/compiled by an expert.
From my experience and research, points were often made on the spot, especially in time of need. That could explain why it was there. Might be some others in the area.
Can see why you picked it up, as the material is beautiful. Did you know it was a point at the time, or did you clean it off and then make the discovery?

Indeed, just over the last couple of months I've been reading about recent (last 15 years or so) digs at several sites on the west coast in the 12-15,000 year range. But I'm about 300 straight-line miles from the coast, and that's some mighty rough terrain. I just said 10k due to the Spirit Cave mummy, which was discovered about 15 miles from where I live now. Don't know much else about the ancient history of the area, other than the many petroglyph sites, the nearest of which (about 10 miles down the road) is about 8000 years old.

I didn't know it was a point, but realized it as soon as I rubbed off the dirt to look at it. That red jaspery-agatey is pretty common here. Usually mixed with other stuff-sometimes run through with lovely clear or white agate. Hard to find large chunks though, except just solid jasper.
