It is 872 kilometres (542 mi) long, and its drainage basin covers 238,000 square kilometres (92,000 sq mi). Including its longest source river, the Sartang , it is 1,492 km (927 mi) long. Its annual discharge totals approximately 35 cubic kilometres (28,000,000 acre⋅ft ). Most of this discharge occurs in May and June as

The Dulgalakh rises on the central Verkhoyansk Range , south of the southern slopes of the Arkachan Plateau . It flows through Kobyaysky and Verkhoyansky districts.

72-483: The Verkhoyansk Mountains (lowlands were always too dry for glaciation) and overflow lakes on the marshy plains in the north of the basin. The whole Yana basin is under continuous permafrost and most is larch woodland grading to tundra north of about 70°N, though trees extend into suitable microhabitats right to the delta. Verkhoyansk, Batagay , Ust-Kuyga , and Nizhneyansk are the main ports on

In 1638–40, 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. In 1892–1894 Baron Eduard Von Toll , accompanied by expedition leader Alexander von Bunge , carried out geological surveys in
96-727: The Verkhoyansk Mountains or the Chersky Range , part of the East Siberian Mountains . Evidence of modern human habitation was found in the delta at the Yana RHS (Rhinoceros Horn Site) as early as 32,000 years ago. These people, designated as "Ancient North Siberians”, genetically diverged 38,000 years ago from Western Eurasians, soon after the Western Eurasians split from East Asians. In 1633–38 Ilya Perfilyev and Ivan Rebrov sailed down
108-543: The Yana. The Yana basin is the site of the so-called Pole of Cold of Russia, where the lowest recorded temperatures in the Northern Hemisphere are found. In the winter, temperatures in the centre of the basin average as low as −51 °C (−60 °F) and have reached as low as −71 °C (−96 °F); in the mountains it is believed that temperatures have reached −82 °C (−116 °F). Yakut folklore says that, at such temperatures, if you shout to

During one year and two days the expedition covered 25,000 kilometres (16,000 mi), of which 4,200 kilometres (2,600 mi) were up rivers, carrying out geodesic surveys en route.

132-530: The greater East Siberian Lowland , shared with the Indigirka to the east. As the river flows into the Yana Bay of the Laptev Sea , it forms a huge river delta covering 10,200 square kilometres (3,900 sq mi). Yarok is a large flat island located east of the main mouths of the Yana. There are approximately 40,000 lakes in the Yana basin, including both alpine lakes formed from glaciation in

In the Verkhoyansk area, it stays frozen to the bottom for 70 to 110 days, and partly frozen for 220 days of the year. The river begins at the confluence of the rivers Sartang and Dulgalakh in the Yana-Oymyakon Highlands . It flows north across the vast Yana-Indigirka Lowland , part of
