I know that I'm a lousy guesser. Somewhere in this thread, I guessed at total cordage. Well, I counted my 1/3 cord stacks, and came up with 6 cord in total, from the three oaks. Many bark shingles still over the rock wall. I'll probably gather them. Once dried out and split, they make OK kindling. Would make for a hot campfirenough with other yard wood. I still have rounds to split. I included them in my count. On to my SIL'S.
