When i first split a piece of this the nice straight grain reminded me of ash BUT the ash trees in my yard are holding these right now.....(see attached pic below). This tree did not have any of this (what do you call this thing anyway??). Also, I've never cut into an ash and noticed a strong scent, this tree had a very strong smell.
Hickory? - I dont know, its not a real heavy wood. Isn't green hickory similar in weight to oak? If so, this is not hickory.
Locust, - Nope, Ive cut plenty of that to know this isn't locust although it does have a thick bark.
Cherry- Nope, its got a smell to it but not as nice as cherry, bark and color are differnt from cherry too.
PA Plumber - this one is not from a wet area, it was near the top of a hill in a fairly heavily wooded area.
