Not every mountain is shaped like a pyramid, with a clear peak. In seven years of research, a team led by Eberhard Jurgalski, the German chronicler of high-altitude mountaineering, has investigated three of the 14 eight-thousanders which, due to topographical conditions, have repeatedly been misjudged by climbers: Annapurna, Dhaulagiri and Manaslu. “It is clear now after all this research and communication that many mountaineers, including some well-known ones, have definitely failed to reach the very highest points on one or more of these mountains, ” writes Eberhard on his webside 8000ers.com.
Take Annapurna, for example: Based on high-resolution satellite images, the German Aerospace Center (DLR) made available to Jurgalski and Co. a profile of the Annapurna summit ridge, which is more than 300 meters long, with centimeter-accurate data on the elevations. There are some of them: besides the “real” 8,091-meter-high summit more than a handful of cornices, which could be and partly in fact were taken for the summit. One of these points is only a few centimeters lower than the summit, while the difference on another is almost 27 meters.
