The (, ; "Five saints") is a mountain massif in Mongolia, near the triple border with China and Russia. Its highest peak, the Khüiten Peak (formerly also known as Nairamdal Peak), is the highest point of Mongolia at 4374 meters above sea level. The Tavan Bogd massif is located mostly within the Bayan-Ölgii Province of Mongolia; its northern slopes are in Russia's Altai Republic, and western, in China's Burqin County. Besides the Khüiten Peak, the Tavan Bogd massif includes four other peaks: Nairamdal, Malchin, Bürged (eagle) and Ölgii (motherland). International borders According to the relevant trilateral agreements and published topographic maps, the junction point of the China–Russia border, the China–Mongolia border, and the Mongolia–Russia border is the top of a peak with the elevation of 4081 or 4104 m, at the coordinates The mountain peak is referred to in the agreements and maps as the Tavan Bogd Peak (, Tavan-Bogdo-Ula; , Tavan Bogd Uul), or Mount Kuitun (). Due to its remote and hard to access location, on a mountain covered with perpetual snows, the three states have agreed not to install a border marker at the tripoint. Other sources claim that the tripoint is called Nairamdal Peak, but this is not confirmed either by official agreements or by maps. Some other peaks of the Tavan Bogd massif are located on the China–Mongolia border or the Mongolia–Russia border. In particular, the massif tallest point, the Khüiten Peak, is located on the China–Mongolia border, about 2.5 km south of the tripoint. In the past, it was known as the "Friendship Peak" (Nairamdal Uul in Mongolian, or Youyi Feng 友谊峰 in Chinese). Peaks The main peaks of the Tavanbogd massif are: Glaciation According to satellite measurements, the total area of the glaciation in the Tavan Bogd massif area amounted to 204 km2 in 2009. The glaciates area was 213 km2 in 1989; in other words, the glaciers lost 4.2% of their area over those 20 years. Out of the countries that share the massif, the largest glaciated area is in Mongolia; it includes the Potanin Glacier (Mongolia's longest) and the Alexandra Glacier. According to a 2011 estimate, the northern (Russian) slope of the Tavan Bogd massif contains 12 glaciers, which cover the total of 22.8 km2. According to the Russian researchers, the glaciers of the massif's northern slope lost 11% of their area between 1962 and 2002, and another 12% in 2002–2009.
