Trying to determine what to do. We are just getting into wood burning and learning. We had a tree fall last year that I cut and stacked the logs (I honestly don’t know the species). They have not been covered or split, and I have not tried to burn anything from this pile. However, I would like to know first of all if it’s a good idea, and if not currently a good idea, is there something I should do with this stack to get it usable? When I first cut up the tree, we did not have a covered storage solution, but we now do. I know I could move it into the wood shed, but there is some kind of shelf fungus growing on the logs. Any thoughts here? Thank you. I have attached pictures.
