Aldan in Depth
Course
The Aldan rises in the Stanovoy Mountains southwest of Neryungri. It flows roughly in a northeast / ENE direction south of the Lena Plateau across the Aldan Highlands, where it forms the northern border of the Sunnagyn Range. Then it flows past Aldan and through Tommot, Ust-Maya, Eldikan and Khandyga before turning northwest. In its last stretch it flanks the southern slopes of the Verkhoyansk Range and joins the Lena near Batamay.
