Description: <...> We were totally unaware of any unusual objects in the sky and really didn't see anything out of the ordinary. After we went back to our hotel I was just zooming the pictures on the digital camera to see if can see any more detail than was visible. To my surprise, in two of the pictures taken of the entrance, I could see some bright objects in what seems to be some kind of formation. These were the only pictures we took in that area and direction.
