Wheat whacker, That is a nice one. I have a smaller one that is similar but yours has such a nice tapered tip to it. Guy, I kick myself after seeing your pic. We had a real nice old tomahawk like that but the rock was broken/split. It was all there just had a fracture. There was some faded red paint on the head. We had an antique auction and put it on there and I forget what it sold for but I wish we would have kept it or at least taken some pictures.
The one in the pic with the hole could either be for making arrows or a weight for a fish net. I met a old feller back in the late 70s while exploring out in the middle of nowhere north of Newtown and he asked what my bride and I were doing and he said hop in. we spent the afternoon with him and he knew a lot and shared a lot. He showed us what he called fossilized dinosaur eggs but I don't know what to believe on the streets sometime.
I am going to hazard a guess that old feller was my step-grandfather. Name was Ed Hansen and he owned a bunch of land up in that area around then. I was probably 10, or so, when he first showed me what he called dinosaur eggs that protruded out of the ground just a few miles north of town.
Note, they aren't dino eggs, but you could sure convince people that they look just like what you would think a dino egg should look like. Those geologic features are way too young for dinosaurs.
