Ust-Mil
Ust-Mil lies beside the Aldan near the mouth of the Mil, a river descending from the Lena Plateau. The Mil crosses taiga dominated by pine and larch before entering the Aldan from the left; its valley contains marshes and many small lakes. In winter the smaller river can freeze through entirely, while the Aldan carries its waters onward toward the Lena and the Arctic sea.
