The Transhimalaya Mountains or Trans-Himalaya are a narrow and long mountain range of 1,600 km (mi) that runs in a west-to-east direction parallel to the main Himalayan range, separating it from the Tibet Autonomous Region and the Tibetan Plateau through India, Nepal, and China. The main feature of the range is its truly cosmic desert-like landscapes of the dry alpine steppes on its territory, surrounded nevertheless by one of the highest snow-covered peaks on earth. How tall they are can be judged by their lowest peak, Azhag Kanglha, which is "just" 4,138 m (13,576 ft). The highest and most prominent mountain is Namcha Barwa (7,782 m / 25,531 ft). In total there are 185 named mountains in the Transhimalaya Mountains.
