The Chersky Range (, ) is a chain of mountains in northeastern Siberia between the Yana River and the Indigirka River. Administratively the area of the range belongs to the Sakha Republic, although a small section in the east is within Magadan Oblast. The highest peak in the range is tall Peak Pobeda, part of the Ulakhan-Chistay Range. The range also includes important places of traditional Yakut culture, such as Ynnakh Mountain (Mat'-Gora) and kigilyakh rock formations. The Moma Natural Park is a protected area located in the southern zone of the range. History At some time between 1633 and 1642 Poznik Ivanov ascended a tributary of the lower Lena, crossed the Verkhoyansk Range to the upper Yana and then crossed the Chersky Range to the Indigirka. The range was sighted in 1926 by Sergei Obruchev (Vladimir Obruchev's son) and named by the Russian Geographical Society after the Polish explorer and geographer Ivan Chersky (or Jan Czerski).
