Not to be too pedantic, but that isn't an arrowhead, although people often call them that. Given the size and shape, that is going to be (most likely) a dart point. The generic term would be "projectile point." If it was an arrowhead, then it would have been on an arrow fired from about a 10' bow, probably by one of the mythic giant races people claimed to have lived in North America. More than likely, that is a dart point as would have been fired from an atlatl. I don't know the chronological typologies for where you are, but atlatls were in use in the New World from 10-12k years ago up until historic times.
Disclaimer - while I was an archaeologist for 25 years, I wasn't a lithicist.
Nice point! I spend a good amount of time each year before the crops cover everything hunting artifacts. Generally speaking, if there's one, there's bound to be more.....good hunting!
I was told, as a general rule, the older stone work was finer finished, more work went into the point.
For the land owners sake, it's not an artifact. Otherwise they wouldn't ever be able to do anything with that field again.
I've spent a considerable amount of time in the creeks and rivers here and they have never been productive for me.I was a very serious collector for many years, some injuries and a bad knee have curtailed my arrowhead hunting activities greatly. We hunt for them in creeks, in our area it's a very productive method.
It does vary quite a bit by the area you're in, if you move down a little further south of the area we creek hunt it's very difficult to find anything due to the creeks being full of deep sand and gravel, and the topography plays a part in that too. For a lot of stuff to get into the creeks there have to be at least parts of sites eroding into the stream beds, and if the banks along the edge of the creek aren't high enough then the sites will be farther away from that edge, and not as subject to eroding in. That's likely the reason we find mostly Archaic and earlier Woodland stuff, the later peoples who had begun to practice a little bit of horticulture (and thus had more permanent settlements) were backing up further away from the creek and less of their stuff was finding its way into the bed loads of the creeks. So you're looking for a specific kind of creek, it needs to have a hard bottom, even if covered with a manageable amount of sand and rock, and it needs to have banks high enough to allow them to have been setting up the seasonal camps close enough to the edge that later stream meander would wash stuff into the creeks. To find stuff in our creeks also requires digging in the sand, you're just not going to find much visually, the stone artifacts tend to sink to the bottom over time so they'll be found along that hard bottom. Many places you can just "coon" through the sand with your hands, but deeper water might require a shovel...these methods work well in the area where we hunt, but may not apply well to other areas.I've spent a considerable amount of time in the creeks and rivers here and they have never been productive for me.
