Why do the Kunlun Mountains have less prominence than some other high Asian mountain ranges?

The Kunlun Mountains have less prominence than other high Asian mountain ranges primarily because they are situated on a high-altitude base. While the range features significant peaks—such as Mount Muztag, which reaches 25,338 feet (7,723 meters)—the surrounding terrain itself lies at an elevation above 16,000 feet (4,900 meters).1

Additionally, the southern face of the Kunlun Mountains rises no more than 5,000 feet (1,500 meters) above the Plateau of Tibet, which maintains an average elevation of approximately 15,000 feet (4,600 meters). Because the mountains rise from this already elevated plateau rather than from low-lying plains, their relative vertical relief is reduced compared to other ranges that rise more dramatically from lower base elevations.21
