I searched the forum and read quite a few posts on how hard Sugar Maple is to split. I have a chance to get a fairly good sized one a couple miles from home. When I hear "Splits Hard" my mind automatically goes to Elm. Have done my share of Elm and come to the conclusion if it comes down to Elm or snowballs I am going to see how many BTUs are in a snowball. On a scale of 1 to 10 (1-easiest 10=Elm) could I get some comments on Sugar and where it would fall in this scale in your opinion. From what I read it seems like a decent firewood that rates somewhere close to Oak.
