That 12" tree, I say 12" but it's probably bigger than that at the butt, is probably a good 200 years old
There are 3 or 4 trees in that group that would be good for bows, straight with no branches for at least 6' and very little twist. There are 1 or 2 that are excellent with practically no twist. There must be at least a dozen tree 6" and over in diameter and another dozen smaller trees. I took pictures of the biggest one and some of the nicer trees. There are a lot that are gnarly and twisted
