its "height must be at least 25,000 feet [7,600 m], and might be anything; it dwarfed all other mountains near it." However, the massif remained unclimbed until 1960. The Amne Machin mountains had been overflown by a few American pilots who overestimated the elevation to 30,000 feet (9,100 m). A 1930 article of the National Geographic estimated the peak elevation to 28,000 feet [8,500 m] according to the report of Joseph Rock, an American botanist and explorer who, despite death threats from the Golog Tibetans, had ventured to within 80 km of the mountain. For a while, the mountains were considered as a possible place for a peak higher than Mount Everest. While Rock only downgraded his estimate publicly in 1956 to "not much more than 21,000 feet", he did give a detailed description of the peaks: By 1980 Anyi Machen had been resurveyed at . Climbing history In 1960, a Chinese expedition climbed the mountain, but it was demonstrated in 1980 that this expedition climbed Amne Machin II (Roche's Chenrezig, 6,268 m), 7 km SSE from the highest summit. In 1981, Amne Machin I (Dradullunshog) was reached near-simultaneously by three groups, each of which had been led to believe they were the first and only ones to obtain a permit from the Chinese government. A Japanese expedition approached the summit from the south and put Giichiro Watanabe, Yoshio Yamamoto and Katsumi Miyake on top on May 22, 1981, and five other expedition members 3 days later. Within three weeks, the American climbers Galen Rowell, Harold Knutsen and Kim Schmitz made an Alpine-style ascent over the East ridge of the NE summit to reach the main summit on June 9. They did not see any evidence of an earlier ascent. The very next day Siegfried Hupfauer, Hans Gaschbauer, Franz Lämmerhofer, Gerhard Schmatz and Peter Vogler of an Austro-German expedition reached the summit as well. They had followed the Japanese route and the 3000 feet of fixed rope they encountered en route convinced them that the Japanese had been the first to summit. The mountain remained busy that summer, as Kim Schmitz returned to the summit with two Canadian clients on June 12, another Japanese party summited in August, and in September an Australian team climbed the impressive NE face and descended over the 6 km long unclimbed NNE ridge.
