Not to question your snake identification skills, but are you sure it was a copperhead? Unless your wood pile was close to a stream or a pond, I can't imagine a copperhead having any interest in a woodpile. They typically don't stray far from their water source. They are in the water snake family.
You might want to alert the copperheads in north Arkansas of this. Most of the copperheads here won't be anywhere near water source. Cottonmouths yes, but not copperheads. I once hit a black snake with a grass trimmer. Slung the sucker right up against me, not fun.
