Geography

The Orulgan Range is one of the main subranges of the Verkhoyansk Range system. It is located in its northern section, running along the main ridge, stretching southwards to the south of the Kharaulakh Range. The Dzhardzhan Range rises to the west and the Sietinden Range to the east, running in a parallel direction, while the Byrandia Range stretches southwards beyond its southern end.[1][2]

The highest point of the Orulgan Range is an unnamed 2,283 metres (7,490 ft) high ultra-prominent summit located in its central section which is one of the highest peaks of the Verkhoyansk Range. The range has 77 mountain glaciers with a total area of approximately 18 square kilometres (6.9 sq mi). The largest glacier is Kolosov Glacier with an area of 4.4 square kilometres (1.7 sq mi).[1][3][4]

Hydrography

The Orulgan Range is deeply cut by riverine intermontane basins with the Undyulyung, Begydzhan, Soboloh-Mayan, Menkere, Dzhapdzhan, Byosyuke and other right tributaries of the Lena River flowing westwards. To the east flow the Omoloy and its left tributaries, as well as the Bytantay, a left tributary of the Yana River.[1]

Flora

The mountain slopes of the Orulgan are covered with sparse larch forests up to heights between 1,000 metres (3,300 ft) and 1,200 metres (3,900 ft), and with rocky mountain tundra at higher elevations.[1][5]
