Kyun-Tas (Russian: Кюн-Тас; Yakut: Күн Таас) is a mountain range in the Sakha Republic, Far Eastern Federal District, Russia.[2]
The Kyun-Tas is one of the mountain areas of Yakutia where there are kigilyakh rock formations.[3] [4] [5]
The Kyun-Tas is located northeast of Deputatsky,[6] between the Selennyakh Range and the western end of the Polousny Range. It rises at the southern limit of the Yana-Indigirka Lowland, northwest of the Aby Lowland. It is a broad massif with mountains of middle height and smooth slopes.[7]
The main ridge stretches in a roughly southeast/northwest direction west of the eastern slopes of the Selennyakh Range for about .[8] Although the range is smaller, the highest summits of the Kyun-Tas are higher than those of the neighboring Polousny Range. The highest peak, located in the northern part, is 1083m (3,553feet) high; there is another high peak at the southeastern end that is 1031m (3,383feet).[7]
The long Nuchcha, a tributary of the Chondon, originates in the range. Also the long Baky, one of the rivers that forms the Uyandina tributary of the Indigirka, has its source in Lake Baky, located at the junction of the Kyun-Tas and the western end of the Polousny Range.[7]
