Wow ! Way to go JYD. With regard to the midden question in the previous replies. I'm, not sure but here in TX, midden is easily identifiable by the cooking rocks. Square broken rock piled up to cook with or create a foundation for living. We find it in layers here. Shell, rock, bone, ash and of course flint. Camps here consist of several areas not unlike a town. There were spots to cook, process game, put your T.P. up, beat out rocks, you name it. I'm not sure if camps were the same there ? I hope I didn't add too much confusion to the midden question? Without a doubt the place your finding this quality on the surface, there will be many whole uncovered treasures beneath. Good Luck !
