ULAANBAATAR: The height of Mongolia’s highest mountain has been re-measured using modern GNSS equipment. The update was conducted jointly by the General authority for land administration geodesy and cartography, the National Climbing Federation, and relevant professional organisations.
The measurement work took place in August and September 2025, utilising high-precision GNSS instruments.
The peak known as Tavan Bogd has historically been recorded at different elevations: some sources list it as 4,104 metres, while Resolution No. 149 of the Council of Ministers (1980) cites 4,082 metres. The new 2025 geodetic measurement places the tripoint or summit at 4,081 metres.
Mount Khuiten, generally accepted as Mongolia’s highest point, has been cited in textbooks and other sources as 4,374 metres (and occasionally as 4,352 metres). According to the 2025 GNSS measurement, its height is now determined to be 4,351 metres.
Mount Munkhkhairkhan has also seen varying reported heights. The 1980 resolution lists it as 4,204 metres; other sources have claimed 4,362 metres. The new 2025 measurement indicates it is 4,196 metres.
Geodetic consultant engineer O.Khosbayar, engineers O. Purevdorj and E. Uranbolor conducted the measurements. For part of the fieldwork, they climbed Mount Munkhkhairkhan and Khar An in a continuous 21-hour effort.
Additionally, to address long-standing inconsistencies in mountain naming, local governments and the National Climbing Federation have agreed to disseminate the official mountain names as approved by Parliament and standardise their use in maps and publications. - Go Go Mongolia
