Brief synthesisThe Petroglyphic Complexes of the Mongolian Altai include three rock art sites in Bayan-Ulgii aimag: Tsagaan Salaa-Baga Oigor of Ulaankhus soum, and Upper Tsagaan Gol (Shiveet Khairkhan) and Aral Tolgoi, both of Tsengel soum. The Petroglyphic Complexes of the Mongolian Altai represent the most complete and best preserved visual record of human prehistory and early history of a region at the intersection of Central and North Asia. Criterion (iii): The Petroglyphic Complexes of the Mongolian Altai Mountain provide an exceptional documentation of the pre-historic and early historic communities in the northwestern Altai Mountains, at the intersection of Central and North Asia. IntegrityThe two largest sites, Tsagaan Salaa-Baga Oigor and Upper Tsagaan Gol, include a unique array of material relating to the Bronze and Iron Ages. The traditional protection by local inhabitants of this region is a key factor in the management of the Petroglyphic Complexes of the Mongolian Altai.
