As already suggested, the timber is of little value, the only chance of getting anything back is if the butt is figured which is not that uncommon, clean, and of good size.
Even then, drying the material is almost impossible. But it can be done in thinner planked section. Even if it is of a quality worth planking, is there easy access, and is there anyone local with a mobile mill. In truth the best you could hope for is someone clearing it for you and taking away or cutting the butt on site. Or you paying them to do it and waiting a few years with fingers crossed it does not check to hell.
Perhaps some sizes and check to see if there are any tell tell signs of figure in the butt. Then i can give you a better idea.
