Chersky Range

Lore & Background

The Chersky Range is significant as a major mountain system in northeastern Siberia, forming a key geographic and tectonic boundary. The range's tectonic position on the boundary between the Eurasian and North American plates makes it an important area for studying continental rifting and compression, though the exact nature of the boundary remains under investigation. Its glaciers and alpine relief contribute to the hydrology of the region, feeding three major river systems. The Chersky Range, along with the Verkhoyansk Range, moderates the climate of Siberia by obstructing west-moving air flows, reducing snowfall in the plains to the west.

Reader's Guide

The Chersky Range is a mountain chain in northeastern Siberia, situated between the Yana and Indigirka Rivers. Administratively, it lies mostly within the Sakha Republic, with a small eastern portion in Magadan Oblast. Its highest point is Peak Pobeda, located within the Ulakhan-Chistay subrange. The mountains hold cultural significance, containing traditional Yakut sites such as Ynnakh Mountain (Mat'-Gora) and distinctive kigilyakh rock formations. The southern zone of the range is protected by the Moma Natural Park. The system was first crossed by a Russian explorer, Poznik Ivanov, sometime between 1633 and 1642, and was later sighted in 1926 by the son of geologist Vladimir Obruchev. It was subsequently named by the Russian Geographical Society after the Polish explorer Ivan Chersky. The range is composed of numerous subranges running northwest to southeast, and its hydrography includes the basins of the Yana, Indigirka, and Kolyma rivers. Some higher alpine sections contain roughly 350 glaciers and small glacial lakes. The range lies on the boundary between the Eurasian and North American tectonic plates; its precise nature remains debated, with earlier interpretations of continental rifting now largely replaced by the view of an active suture zone where compression occurs, making the region seismically active.
