I just got finished cutting, splitting, and stacking next year's firewood. Wish I was farther ahead, but I'm not; this is what I've got and this is what I have to deal with. I've got 16 pallets under the wood in a 4x4 patern (the pile is 16' square), then tightly stacked 5' high. Its stacked in a relatively sunny area that gets as much breeze as there is. The wood is generally split to the equivalent of 5"~6" diameter by 18" long in size. It is mostly elm with white oak, maple, and wild cherry making up the rest. Does it make sense to put a tarp over the top of it (not covering the sides other than to drape over them slightly) or not?
