In all seriousness between milling and pulp wood is my guess on those stacks and as for the water I think it’s to keep the piles from starting on fire
Actually what I have heard is it is to keep the wood from drying out too quickly and checking too much. Gradual drying as they arent worried about mold. If its to be milled that is!

No doubt. Could definitely be a combo of both milling and pulp with particle wood. Pines be the likelihood.
