I've only come across a few pieces of this over the years. The last time it was a tree already cut down and brush cleared so no leaves to examine. My friend more knowledgeable about trees calls it Swamp Oak. I made and sold a few items from it using that name. I came across two more pieces recently and again, no leaves to see. It was on a pile of logs from a cleared lot. I've looked online and I don't really see a lot of consistency in pictures of wood to be certain. The look is the same as before - pale sapwood and deep brown heartwood. I really like it and want to be on the lookout for more. I kow there are LOTS of different types of oak so hard to be sure sometimes. Some wood pictures of Pin Oak do look exactly like it, some don't.
