Ruins of Desert Cathay 243 - View to west towards Shagolin-namjil peaks from Su-lo Ho - Pei-ta Ho watershed. Both rivers flow toward the north with the Su-lo Ho being further west - The Pei-ta Ho eventually exits the Nan-shan and joins the Kan-chow at Mao-mei to flow north, forming the Etsin-gol to the Chinese-Mongolian border. (The left border of this photo joins the right border of the following photo.)
