a mountain range in the western part of the Vostochnyi Saian in Krasnoiarsk Krai, RSFSR. Length, about 250 km; elevation, to 1,732 m. Medium-altitude mountain terrain predominates. The mountains are dissected by the Mana, Shinda, and other rivers of the Enisei Basin into parallel, flattopped massifs. They are composed of Proterozoic and Lower Cambrian metamorphosed sandstones and limestones cut by granite intrusions. There are pine and larch forests on the slopes to elevations of 600-700 m and fir, spruce, and cedar taiga above that. Above elevations of 1,400-1,500 m there are sparse forests of cedar and fir, with areas of subalpine meadows and tundras, which, together with the snowfield, cover the peaks of the mountains (hence the name belogor’e, “white mountains”).
