I am not sure. Maybe Black Locust or American Elm. I don't think it is poplar. The only poplar with bark like that is Cottonwood, which is not common this far east.
Welcome to FHC Nocattom .... Not real sure, Wood Duck has a couple of good idea's. Can you get us a fresh cut and a split to give a few better clues. Just not enough clues to fully say for sure.
The bark is a choclate brown where it has broken. Reminds me of black walnut, but the wood doesn't look like walnut. Kind of reminds me of Linden(basswood).
Welcome to the fun Nocattom! , you found the best place on the web for wood, food, and fun and some other stuff as well! We are very glad to have you. Now, What you "May" have there is good old east coast "black gum"! and Wood duck is on the money. You'll know when you "TRY" to split it! If it's Gum or Elm. Looks like it to me, a pic of the leaves would give it away. Was there a lot of "spikey" balls around the tree, thats the gum seed.
There is sweet gum all over the place around here in Maryland. I'll see if it's splitable and take another pic. And thanks for the welcome.
Yup! Know it well, over here also! Good burning wood, not "bad" BTU's just a Son of a B!T@H to split!
its either siberian elm or american elm. break off a piece of the bark and look for alternating layers of creamy white and redish brown. if it has those layers then its american elm. if not then its siberian elm. it will be stringy. css it up off the ground and it will be ready to burn next winter. if you let it sit 2 years it will start to rot.
