A landscape that bears the imprint of two or more sets of geomorphological processes. For example, much of the Sahel region of Africa shows land-forms resulting from former wet and dry episodes. The word is derived from the Greek palimpsestos, ‘to rub smooth again’, and is also used for a re-used parchment, paper, or ornamental brass whose original writing or engraving has been only partially erased and for a sedimentary structure in which one set of trace fossils has been partly overwritten by another.
