Thanks for the responses. Hoping to get back out to the site to do some more searching. It’s in an area where we found a cave that I believe was the one David Fanning used back in the American Revolution so a lot of good history in the area. Wish I knew somewhere around here in NC to be able to get something dated.
It's frustrating. I have an area that is of the similar time frame and find things that I really can't make heads or tails of and likely most can't either due to condition. If I feel it is worthy, I remove it, but if not something that doesn't make any sense to me, I just put it back so that hopefully someone else comes across the find that has more knowledge than I. However, I love the removing the modern trash aspect and cleaning up the park of more modern junk like pull tabs or modern beer glass etc.
