Chipped Bark

While I was at Scherman Hoffman Wildlife Refuge on Saturday, I cam across a tree that had obvious damage to its trunk. A large section of bark was stripped away, and the wood underneath was chipped in a square-edged pattern. I was curious what would cause this pattern. The damage was too high to be the work of beavers. It is about the right height for deer, but would deer chew the wood underneath as well? Could a person have done this? The same pattern was not evident on nearby trees, so whatever did the damage was attracted to this particular tree.
