I think that what he is referring to is also known as red maple or soft maple. (Acer Rubrum). It's one of the more common hardwood species up here, and has about the same amount of BTUs as white birch.Nice pile of firewood you have pulled out OldPath. I had to look up white maple - never heard of it. Found out it is silver maple or swamp maple, which we have here. Tree names with local variations are confusing.
