Tuoydaax
Tuoydakh lies on the right side of the Vilyuy valley, northeast of Lake Mar-Kyuyol and across the river from the country around Suntar. Here the Vilyuy makes a great bend through the wooded lowlands of western Yakutia. Lakes and channels accompany the river as it turns eastward toward the Lena. Long winter ice gives way to a brief summer season of flowing water.
