Yaks' Land is a term used to refer to the Tibetan Plateau, which is located in the Himalayan Mountains of Central Asia. It is the highest region on Earth, with an average elevation of 4, 900 meters (16, 000 feet). The plateau is home to many species of wildlife, including yaks, and is the source of several major rivers, including the Yangtze, Yellow, and Mekong. Tibet, the region's largest country, is also known as the 'Roof of the World' due to its high elevation.
