They are all dug. I'm digging the slightly higher spots with the blacker soil which is where I'm finding a lot of the flint, animal bones and whatnot. There does seem to be a lot of broken artifacts so I'm not sure if they are scrap piles or stuff just thrown in the fires. Last few digs have only been about 6 inches down, but I have found broken artifacts in the deeper spots too. No farming or modern activity here to my knowledge. I suppose its possible with the shallower artifacts that there was "disturbance" of some kind at a later date .
As far as digging goes you can't touch state land here, but permission on private property is ok which I thought was the case country wide for most part. I also kind of lucked out on the farmer not caring about artifacts.
Yea, no worrying for me, but I do respect the hunters even though I have permission to go anytime. Its a big lot of land and I know he has so many people wanting to hunt it during shotgun season that he does a lottery type deal to decide who can hunt for the year. I imagine he has a handful of bowhunter's looking to come out soon. Once they harvest corn and I can get to the oak I was finding pottery around I will be hitting that spot again
I like finding there fire pits and sifting through it . Usually find a lot of broke artifacts sometimes whole ones. I find a lot of small animal bones also. Believe it or not I have found charcoal down 2 to 3 feet deep the dirt would have greasy animal fat smell to it.
