Üöhee Amma

Üöhee Amma, or Upper Amga, lies on the river's upper course in the forested uplands of southern Yakutia. The Amga rises in the Aldan highlands and flows across the Lena plateau, eventually reaching the Aldan. Its basin contains thousands of streams and lakes. The river freezes in autumn and opens again in spring, with some stretches freezing through in the harshest cold.
