Atka

Atka lies in the mountainous interior north of the Sea of Okhotsk, near the headwaters of the Yama. The Yama begins where the Maymandzha and Maymachan meet on the southwestern slopes of the Maymandzhin Range, then flows toward Shelikhov Gulf. Nearby headwaters drain in the opposite direction toward the Kolyma. Forested valleys and high ridges divide the coastal watershed from the great rivers of northeastern Siberia.
