evidence: Tajik National Park (Mountains of the Pamirs) [...] Tajik National Park (2,611,674 ha in area) encompasses almost the entire Pamir Mountains, the third highest mountain ecosystem in the world after the Himalaya and Karakorum Mountains. The Pamir Mountains lie at the centre of the ‘Pamir Knot’, the term used by geographers to describe the tangle of the highest mountain ranges on the Eurasian continent. Huge tectonic forces stemming from the collision of the Indian-Australian plate with the Eurasian Plate have progressively thrown up the Himalaya, Karakoram, Hindu Kush, Kunlun and Tien Shan – all radiating out from the Pamir Mountains. Along with the Karakoram Mountains, the Pamir region is one of the most tectonically-active locations in the world. [...] Criterion (viii): The Pamir Mountains are a major centre of glaciation on the Eurasian continent and Tajik National Park illustrates within one protected area an outstanding juxtaposition of many high mountains, valley glaciers, and deep river gorges alongside the cold continental desert environment of the high Pamir Plateau landforms. An outstanding landform feature of the property’s geologically dynamic terrain is Lake Sarez. It was created by an earthquake-generated landslide of an estimated six billion tonnes of material and is possibly the youngest deep water alpine lake in the world. It is of international scientific and geomorphological hazard significance because of the on-going geological processes influencing its stability, and the sort of lacustrine ecosystem which will develop over time. Tajik National Park furthermore offers a unique opportunity for the study of plate tectonics and continental subduction phenomena thereby contributing to our fundamental understanding of earth building processes.
