Glad to hear there is some dry stuff in there. Check it carefully, however. A lot of wood will stay wet even if dead and in the tree. I just cut up an Ash log that was down about 3 years and the inside was still very wet. Not just green, but wet to the touch. Same thing with standing dead trees. Somehow I don't think you'd enjoy a chimney fire.
Cover it while it dries if you can. It helps more than most folks think. Air drying is good, but keeping the rain and snow off really makes a big difference.
What kinds of trees were they? It all burns, but I really treasure locust above all others, even more than my hickory and oak. It burns hot and long with very little ash residue. I've gotten so I think of soft maple as almost junk wood, not much better than pine. Still, I have a lot of it, so I use it when it isn't seriously cold out.
