ridge-and-ravine topography A landscape consisting of a monotonous network of branching valleys and intervening low ridges, and which is similar to that of a maturely dissected peneplain (see DAVISIAN CYCLE). The term has been introduced, however, to avoid any genetic implications. It is well displayed in the central Appalachians, USA.
