In Vietnam I saw the marble mountains. And decided to climb one of them. When I got to the top, I was very tired and sweat was streaming down my face, but I was very happy to see other people there, whom I asked to take my picture. The view from the top was breathtaking and I now know what mountains are used for marble. Have you ever seen marble mountains? Vietnam, Da Nang, 2013
