Thanks for the replies. Was hoping it was something old. My dad told me that the French and Indian war was taken place around where we camp. Was up there this weekend trying to learn on my new at pro. Guess I've found nothing yet. But around where I was detecting there were 3 big rock piles. Bad 4 feet high and around 6foot in diameter. Still no idea who or why they are there. The mountain across from us is supposed to have some old bunker or foundation of one. Didn't have a chance to hike there this time but I will on July 4th when I go.
