The Yudoma-Maya Highlands (Russian: Юдомо-Майское нагорье, romanized: Yudomo-Maiskoye Nagorye;[1] Yakut: Юдома-Маайа хаптал хайалаах сиринэн, romanized: Yudoma-Mâya xaptal xayalâx sirinen) are a mountainous area in the Sakha Republic and Khabarovsk Krai, Far Eastern Federal District, Russia.
It was first surveyed in 1934 by geologist Yuri Bilibin (1901—1952) together with mining engineer Evgeny Bobin (1897—1941) in the course of an expedition sent by the government of the USSR.
Bilibin and Bobin made a thorough topographic survey of the mountainous regions leading separate research parties.
[2] The Yudoma-Maya Highlands lie at the southern end of the Sakha Republic and the western limits of Khabarovsk Krai.
The highlands reach the valley of the Okhota River to the east, and to the south they are limited by the northern end of the Dzhugdzhur Range.
