Tongulakh
Tongulakh lies in the valley of the Sinyaya, a left tributary of the Lena in central Yakutia. The Sinyaya flows across the forested Lena Plateau, cutting a course through uplands west of the great river. In its lower valley, cliffs and pillars of rock stand above the water. The long Siberian winter freezes the river, while the brief summer opens its channels among the forests.
