Geography edit
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 2,246 metres (7,369 ft) high summit located in the central zone.[1]
