Erosion Remnant

a topographic feature that remains after a highland region has been destroyed by exogenic factors. Three types of erosion remnants are distinguished: (1) degradation remnants, which are composed of rocks resistant to weathering and denudation; (2) mesas, which are table mountains that are the remaining parts of an earlier plateau; and (3) meander cores, which form when a river breaks through the neck of an incised meander and isolates a meander lobe.
