I have seasoned maple in the pile anywhere from 1.5 to 2.5 years sitting. On many (most) splits the bark just falls off in one big chunk as I'm grabbing it up for the inside fire. I used to throw them around for my retriever (it was one of his favorite games). Now I just toss them off to the side, like scrap, and throw them in the outside fire later on. Is this a waste of good heat? Should I be burning all this stuff in the inside stove? How is a pile of bark vs clean wood as far as creosote, etc. is concerned...?
