Here are a few things I found that didn't make the cut. I use them in the yard for interesting decorations. Some hammer stones, broken celts & points, pottery etc. The tube looking stone is a fulgurite.
I found one of them hammer stones the other day in the field. When I saw it I said to myself I hope its just a rock cause I cant leave them divot stones and sure enough a divot on each side. Had to rescue it and bring it home. Not real sure what they used them for 100% so I always keep them.
