The Sunnagyn Range (Russian: Суннагын), also known as Aldan-Uchur (Russian: Алда́но-Учу́рский хребе́т; Yakut: Алдан-Учур), is a range of mountains in North-eastern Russia. Administratively the range is part of the Sakha Republic, Russian Federation.[1]
The Sunnagyn is the highest subrange of the Aldan Highlands of the South Siberian System. It rises at the northeastern edge of the highlands, south of the right bank of the Aldan River, between the valley of its tributary Timpton to the west, and the Uchur to the east. The Gynym, a tributary of the Uchur, marks the southern border of the range.[1] [2] [3]
The mountaintops of the range are dome-shaped or flattened and the highest point of the Sunnagyn is an unnamed 2246m (7,369feet) high summit located in the central zone.[1]
The mountain slopes and the river valleys of the Sunnagyn Range are covered with larch forests. Thickets of dwarf cedar grow at higher altitudes and mountain tundra above the treeline.[1]
