Oimiakon
Oymyakon lies in a valley among the mountains of northeastern Siberia, between the Chersky and Suntar-Khayata ranges. Its inland position and enclosing highlands contribute to a sharply continental climate, with exceptionally cold winters and great seasonal changes. Some springs remain unfrozen even in severe frost, while glaciers endure in the surrounding mountains. The valley belongs to the upper Indigirka country, whose rivers ultimately flow toward the Arctic Ocean.
