Nanga Parbat means "Naked Mountain" is so named because some of its slopes are so steep that they are bereft of vegetation and snow. The core of Nanga Parbat is a long ridge trending southwest-northeast. The ridge is an enormous bulk of ice and rock. It has three faces, Diamir face, Raikot and Rupal. The south western portion of this main ridge is known as the Mazeno Wall, and has a number of subsidiary peaks. In the other direction, the main ridge makes arcs northeast at Raikot Peak (7,070 meters). The south/southeast side of the mountain is dominated by the massive Rupal Face, noted above. The north/northwest side of the mountain, leading to the Indus, is more complex. It is split into the Diamir (west) face and the Raikot (north) face by a long ridge. There are a number of subsidiary summits, including North Peak (7,816 m) some 3 km north of the main summit. Near the base of the Rupal Face is a beautiful glacial lake called Latbo, above a seasonal shepherds' village of the same name.
