Looks like Honey Locust - the bark can very closely resemble maple. Looks like a big one! Is there any more of it? Get all you can!
Sure looks like honey locust to me! And like Shawn said, that's a big one I've only ever seen a few that big! Sweet score!
Nice load. I hope you have one of those back things like they wear at Lowes or Home Depot? Those rounds made me think of mine right away!
Not sure you ever will in this part of MI either. And yes, the bark does resemble maple but not the grain.
Just look at the btu charts. The higher the btu's, the heavier the wood. It's up there, above oaks, and sugar maple, but below the btu Kings like Osage orange and shagbark hickory. It's planted in a ton of cities around here, especially between the curb and sidewalks.
