The Upper Kolyma Highlands are located in the upper course of the
Kolyma. They are bound in the west by the
Tas-Kystabyt and
Suntar-Khayata ranges and to the east by the
Seymchan-
Buyunda Depression to the north and the
Ola river basin to the south, with the
Maymandzhin Range stretching in between. To the northwest lies the
Nera Plateau and in the north the highlands merge with the southernmost chains of the
Chersky Range. The
Seimkan Mountains and the
Igandzha Massif rise to the south, among other minor ranges. The highest point is high
Gora Snezhnaya. Another important summit is high
Pik Aborigen, both in the
Angachak Range. The main rivers in the highlands are part of the upper basin of the Kolyma River, including rivers
Ayan-Yuryakh and
Kulu, as well as the
Buyunda,
Bakhapcha —with the
Maltan,
Byoryolyokh and
Tenka, among others. There are
mineral water springs. ==Flora==
