I cut and split about three cords of white oak tops this time last year. It's stacked in a single row, east / west with full sun and near constant wind. I left it uncovered until late last fall and then only covered the top through the winter. Tested a couple splits from the stack. The smaller pieces were still 25-27%, the medium to large splits were over 30%!! I was hoping to burn it this coming season. I only have about 1.5 cords of ash and another cord of mixed, fully seasoned wood. We'll see how the oak looks midway through next season, but I'm not holding my breath. Hopefully I can scrounge some dead ash quick and get it split. I guess it's a sign of a true wood hog that I'm immediately planning next season just as this one is drawing to a close.
