First pic, those three look pretty shot. Second pic, may just be rotted sapwood, solid middle, but I can't tell.
Third pic looks pretty much like the stuff I'm burning right now, after picking up a Red Oak stack crash that got rained on for a couple months before I picked it up. A little mold or whatever on the ends of the splits, no big deal. Some of the sapwood on it might be a little soft, but a lot looks OK. It looks pretty dry as well.
Anyone who says this load is all trash doesn't know wood very well. Is it "really nice?" No, not if "30% ....no weight left, soft"
What did you pay? If your back was against the wall, you gotta do what you gotta do, and you were lucky to find anything that was even
that dry.
When they heap wood in a pile, the inner stuff on the bottom is going to be like that..It's not their fault you didn't know that. That top stuff is "really nice" though.
Next time, say you want the clean, dry stuff on the top, you are heating with wood and your stove will only work with dry wood, blah, blah, blah, etc, etc..
