The Khangai Mountains (/kəŋˈɡaɪ/ kəng-GY)[a] form a range in central Mongolia,[1] some 400 km (250 mi) west of Ulaanbaatar.
The mild climate area where the two provinces meet (in eastern Khangai) is known as the cradle of Mongolian and nomadic civilization.
The plains at the foot of the eastern Khangai host the Orkhon Valley World Heritage Site.
The mountains feed the rivers Orkhon, Selenge, Ider, Zavkhan and the lakes Orog and Böön tsagaan.
[2] Because of strong winter inversions which have become known as a singularity of the mesoclimate of Mongolia (Gavrilova 1974) the Khangai tends to be some 10°C warmer than the surrounding areas.
