Long story short, was told this was red oak. The homeowner got part of it right, in that there was a single piece of red oak off to the side that I split with wedges and a Fiskars. However, the Fiskars bounced off of this stuff as did the wedges. I tried starting the wedges with a 4 lb hammer and even that was tough. Even when I got them started, one shot with the sledge hammer and they were flying out of there. I had a 2 hour window to get wood this morning because my wife needs to attend a baby shower, and I figured since this was an entire red oak that had been felled I would just load up the small pieces, split what I could, and load up the truck in those two hours. So, I left the splitter at home. Man, I am not in a good mood now. I have a guess as to what this wood is, but I don't want to influence anybody's opinion.
