you beat me with the enhancement...
oh well, check out what almost looks like a cord going to the back of the box. Sure it could just be the edge of the rock that this alleged box is
sitting on but almost looks like it was/or is "plugged in".
maybe (if this is something other than a rock..) that bright edge on the mentioned by the poster above is a gear/electrical box of some sort
anyways, nice find though!
