Hate to have to agree with the others, but they are right, your find is just the shape that has been formed naturally. I'll use several photos
in order to show you what I'm talking about, and what you should be looking for. Arrowheads come in many shapes and sizes, and the
first picture shows a point that is a proper shape, and it looks smooth. That's because of the lighting in the photo, the point is not smooth,
it has been flaked into that shape, which might throw a person off, because sometimes the flaking is hard to see in a photo.

The next picture is just to show a couple of different styles, and the black one is flaked out of obsidian, which is volcanic glass and not available
through out the United States, but it shows the flaking really well. Both of these were found in the desert near the same location, so the early
people used what was available, and no certain stone was used, but it has to be a glass or flint like stone in order to shape properly by flaking
off the unwanted parts.

And last, this is what you are looking for, and if you look enough you will be able to spot it from a distance. You are looking for the flaking done to
make the point. You don't always see the entire point, so looking for a shape works, but you would miss a lot, because not all are laying on top of
the ground. If you don't want to be bending over all the time, looking at shapes and what resembles flakes, carry a stick and any suspicious stone,
flip it over, get it out where you can see it. But mostly this last picture shows you what you are looking for, the flaking that shows it's been worked.
The point can be made from lots of different types and colors of rocks, but they all have the flaking in common. Hope this helps.
