The Inner Mongolia Autonomous Region is primarily an inland plateau characterized by a flat surface that lies at an elevation of approximately 3,300 feet (1,000 meters) above sea level.1

While this central plateau maintains that general elevation, the region's topography is varied: its southern boundary is defined by high ridges reaching between 4,500 and 6,000 feet (1,400 to 1,800 meters), and the Greater Khingan Range in the east rises to elevations of 4,000 feet (1,200 meters) and above. More broadly, the larger Mongolian Plateau, which encompasses Inner Mongolia, ranges in elevation from 3,000 to 5,000 feet (915 to 1,525 meters) above sea level.12
