Main image

The Tannu-Ola mountains are a mountain range in southern Siberia that form part of the highlands along the border region between Russia (Tuva) and Mongolia.

The Tannu-Ola region has long been part of the cultural and pastoral geography of southern Siberia and western Mongolia, with local routes and settlement patterns shaped by the mountain barriers. Geologically the range is part of broader Central Asian orogenic structures.

  • Geographic role: Forms a mountain barrier along southern Tuva and runs roughly parallel to the border with Mongolia, influencing local climate and river catchments.
