Central Asia's Tibetan Plateau is justifiably nicknamed "the roof of the world"—its average elevation is more than 4,500 meters (14,764 feet). It is the world's highest and largest plateau, covering an area roughly four times the size of Texas. Tectonic forces have long shaped the Tibetan Plateau's crumpled and uplifted mountain ridges. This scene also features some of the area's deep, glacier-fed lakes. The two largest lakes in this scene are Migriggyangzham near the upper left and Dorsoidong just below it.
