The Sayan Mountains and the Yenisei River, Russia69.4N 86.1E
The Sayan Mountains are a mountain range in southern Siberia, Russia. The Eastern Sayan extends 1000 km from the Yenisei River to the southwest end of Lake Baikal. The Western Sayan forms the eastern continuation of the Altay Mountains, stretching for 500 km to the middle of the Eastern Sayan.
Here, part of the Eastern Sayan in Krasnoyarsk Krai is visible, bordered by the Yenisei River (lower left) and several lakes. The largest lake visible is Khantayskoye Reservoir, situated between the river and the snow-capped mountain peaks.
The Sayan Mountains’ towering peaks and cool lakes southwest of Tuva give rise to the tributaries that merge to become the Yenisei River, one of Siberia’s major rivers, which flows north over 2000 miles to the Arctic Ocean.
While the general elevation is 2000 to 2700 m, some of the individual peaks, consisting largely of granites and metamorphic slates reach altitudes of over 3000 m, with the highest being Munku-Sardyk at 3492 m.
From the Mongolian plateau the ascent is on the whole gentle, but from the plains of Siberia it is much steeper, despite the fact that the range is masked by a broad belt of subsidiary ranges of an Alpine character.
