From space, the opening looked like an ant hole in a pile of sand.  It was difficult to believe that it was actually more than two hundred metres across.  Whatever had dug it out must be some size.  It was hibernation season so the chances were that its occupant was still inside.  The problem was that my orders were to find out exactly, with photographs if possible.  An assessment would then be made but my guess is that the human race had started on the path to wiping out yet another species.
