What is this???

[SeaninNH]

I'm hoping you experts can give me some info on this.

Is it man made or natural?

It was found in a New Hampshire river that was regularly traveled by native Americans.

I walk this river every day during my smoke breaks and today this jumped right out at me.

Thanks in advance for any information you can give.

I see no layers of different rock in the high ridges or the median edges. There's no reason for water to wear unevenly on an igneous rock that appears to be consistent throughout. I believe they are man made, and worn by the river like any other river rocks. I have a river worn net stone that looks the same way, bumpy, no evidence of grinding marks because the rock is worn badly. Congrats on the find!

Cheese!! you have a lot more posts than i do so would you help me to learm about our hobby? by posting photos of any igneous rock artifacts that you have found in a river. Terry.

Cheese, that is the reason I feel mine is man-made. The rock is uniform throughout--no layer of different material around the ridge. I'm no expert by any stretch, just my gut feeling.

My thought as well. It seems to me that it is too uniform to not be man made. I can imagine if it was in the river for a few hundred years it would wear away significantly. Wearing all signs of being man made away. It was found in a fast moving river that they divert for cooling a power station so it goes up and down every few days. One day it's a fast moving river that would wash a car away. The next day you can walk across it.

I've been walking a 40' strip of the river every day for 3 months.

About the piece...

It seems like this is only part of the piece. It seems like it broke off.

Also the ridge goes all the way around the piece and it's even. I would think if it was natural the ridge would not go completely around as evenly.

If you notice, it is tapered on one side like a blade.

I'll some more pictures of some other angles when I can get a chance.

Definitely something that will make you look twice. I've seen a lot
of rocks like this in different sizes where you'll see a vein that is
harder and won't dissolve as fast along the outside of the rock. The
worst ones are the ones that have two veins that are close together
and look like a groove of an axe. Some bigger type boulders you'll
see many protruding veins or layers that stick out the outside of the
surface.

For what it's worth (my opinion is worth nothing, I'll save you the suspense) I believe that is not an artifact for many of the reasons already stated.

I've had the good fortune of handling thousands of axes and I'm 100% sure that it's a natural rock. I've also found pieces exactly like that. Most of the time it's softer stone that's eroded away leaving a ridge. I found one that had a perfect groove in it but it was simply natural.

But, if you want to believe it's an axe you're more than welcome to.
