Scored a massive dump of wood from a local golf course. Been working it the past few months. Almost through it!
I am not the one to ask unfortunately. I thought there was some Elm, and did not know there was any maple.
I just watched a video on how to identify Ash, and those leaves sure look like what I saw in the video, as well as the diamond shape of the bark, so I think you may be right. If that is the case, i am going to be super excited to get that in the stove on the coldest days, as I heard it burns very hot, and does not need as much time to season as other woods.
Yes its great firewood. I recall a few years back someone took a survey of your all around favorite firewood and ash won hands down Dries in a year if cut green. Dead/down a lot less if its not RTB akready. Sad the EAB has decimated them.
