Kystatyam
Kystatyam lies near the meeting of the Kystatyamka and the Lena, in the northern part of the central Yakutian lowlands. The smaller river flows south from Lake Dyanda to join the Lena, hundreds of kilometres above the great river's mouth. Forest and waterways mark this part of the valley, where the Lena continues northward toward its Arctic delta and the Laptev Sea.
