Sayan Mountains

The Sayan Mountains are a mountain system in southern Siberia and northern Mongolia, comprising the Western and Eastern Sayan ranges.

Western Sayan: A mountain range in southern Siberia forming the western part of the Sayan Mountains. It is the system’s western division, separated from the Eastern Sayan by the Yenisei basin.
Yenisei River basin: The drainage basin of the Yenisei River and its tributaries across Mongolia and Siberia. Sayan headwaters feed major tributaries that carry water north across Siberia.
Munku-Sardyk: The highest peak of the Eastern Sayan, on the Russia–Mongolia border. It is the highest point of the Sayan Mountains as a whole.
Siberian Craton: An ancient, stable block of continental crust underlying much of Siberia. Its southern margin borders tectonically complex mountain belts that include the Sayans.
Kuznetsk Alatau: A mountain range in southwestern Siberia, west of the Sayan Mountains. It is a neighboring range, but lies farther northwest and is not part of the Sayans.
Eastern Sayan: A mountain range extending across southern Siberia and northwestern Mongolia. It forms the Sayan system’s eastern division and reaches toward Lake Baikal.
Angara River: A major Siberian river flowing from Lake Baikal into the Yenisei River. Rivers rising in the Eastern Sayan contribute to the Angara’s headwaters.
Ergaki Nature Park: A protected mountain landscape in the Western Sayan of Krasnoyarsk Krai, Russia. Its alpine terrain is a prominent protected example of Western Sayan scenery.
Central Asian Orogenic Belt: A vast region of crustal growth and mountain building extending across Central Asia. The Sayan ranges belong to this broad and geologically complex belt.
Khamar-Daban: A mountain range south of Lake Baikal in southeastern Siberia. It borders the Eastern Sayan region but is generally treated as a distinct range.
