Mount Sanford. Mount Sanford was attempted by two Japanese expeditions in 1976. A five-man-and-a-woman expedition climbed the north ridge. From Camp IV on April 24, 1976 Masaru Nakagawa, Minoru Naka, Tomotsu Ohfuji and Ms. Kazuko Ohmori reached the summit. A four-man party led by Masaoh Nishigai retreated from some 500 feet below the summit on May 8 in bad weather.
