The Moma Range extends from NW to SE for almost southeast of the southern end of the Selennyakh Range and north of the Ulakhan-Chistay Range, the highest subrange of the Chersky Range system. It is parallel to the latter and separated from it by a wide intermontane basin, where the Moma River flows from the southeast and joins the Indigirka. Turning northwards, the Indigirka River cuts deeply across the range in its northwestern part. The Aby Lowland, part of the Yana-Indigirka Lowland, lies to the north and the Alazeya Plateau to the east.
