if its high and low, its probably just the bark falling off a dead tree. thats what it looks like if you look above teh "rub" looking thing could be a rub, but i'd have to see it first hand to decide. another reason i woudl say its not a buck is because none of the other trees are molested. there should be at least some antler marks on those trees. a good buck would probably rub them trees all up, not just pick one out and rub the heck outta that. i've never seen a little set of trees in which just one of them has had the snot rubbed out of it while the others stand there a ok.
