Hey there, Ohi-hunter!
Just wondering if you have found any anvil stones down where you are? I have a couple smaller, flattened stones, that are more commonly referred to as nutting stones. These have a depression on each side.
What I refer to as an anvil stone is more like a workbench of sorts. The one I found on the banks of the mighty Ohio is about the size and shape of a large loaf of bread. It weighs about 25 lbs. It has 2 working sides. Both of the work surfaces have multiple depressions. Some are smooth and round, and some are conical, with some having angular lines or gouges in them. I have had trouble finding examples on the net. The only other place I have seen any, was when I went down to Fort Boonesboro.
I assume that it was used at a long term campsite or village. I also figure that it is probably an implement that would be more exclusive to a river site, such as the Ohio, because of the fact that most points were manufactured from water worn flint nodules, that are found in the river.
Just looking for any input you might have on these ideas.
Thanks!................HH..........And; Nice finds!
