Description :
The combination of meanders, deep gorges, and transverse cuttings is considered as the main geomorphic feature of the upper Huang He. The belonging landforms reveal remnants of former landsurfaces which appear as plateau flats, summit levels, and rock-cut valley terraces. They are interpreted as relics of planation surfaces, pediments, and valley bottoms. The most widespread remnants are the plateau flats between 4,200 and 4,600 m. The planation levels are connected with the stages of the Cenozoic tectonic evolution of the Tibetan Plateau. The upper Huang He drainage pattern is explained by an antecedent development of separate valley units.
