The ecoregion has an average altitude of 2,000 to 2,500 meters, with higher peaks rising 4,031 meters at Mt Otgontenger on the western edge of the range. At lower altitudes, the ecoregion is completely surrounded by the Selenge-Orkhon forest steppe ecoregion, except for a thin band of the Khangai Mountains conifer forests on the northern slope of the Khangai's Tarbagatay Range. The alpine meadows tend to be flat, and the origins of the Orkhon River and Selenge River are in the region. The topography reflects multiple periods of glaciation, although there are currently no permanent snow fields in the range outside of Otgontenger.
