Looks to me like the bark and sap wood are gone on most of it......once the tree dies, the bark comes off and the sap wood hardens and darkens off
I'm in the black locust camp. Color of the fresh splits looks right. In one pic there seems to be a bit of bark remaining. And I'm not surprised that there's very little bark to go by since it falls off readily and in big sheets once dead.
It's there in OTE="blujacket, post: 612812, member: 53"]It very well could be Black Locust, but I'm not seeing the white cambium layer in those pics, and all the Black Locust I've gotten has it and a greenish hue to it when split. I still believe it's Mulberry. Either way, awesome firewood, and I get some every year [/QUOTE] It's there in the second group of pictures in the third picture. Could be a mixed load but I still think its black locust. That's my story and I'm stiking to it.
Black locust, for sure. I cut a ton the looks exactly like that....there's a little scrap of bark on one of the pictures that confirms it.
These things split great! I've been working on some maple that is absolutely nasty - probably takes me 4 times as long to hand split as this stuff.
