The Pamir Mountains are a mountain range in Central Asia formed by the junction of the Himalayas, Tien Shan, Karakorum, Kunlun and Hindu Kush. Since Victorian times they have been known as the «Roof of the World», as they are among the world’s highest mountains. One of them is Khan Tengri (Uighur for «Lord of the Spirits», «Ruler of the Sky»). Only thanks to its glacial cap the mountain is actually taller than 7000m; the rock itself only reaches up to 6995m. Nevertheless , it is officially recognised as a seven-thousander.
