driftless
This term is a highly specialized geological descriptor used almost exclusively to describe terrain that escaped the scouring and depositional effects of Pleistocene glaciers. It evokes an image of rugged, ancient topography where the original bedrock contours remain intact, creating a landscape of sharp ridges and deep ravines rather than the flat, sediment-heavy plains typical of glaciated regions.
In a geographical context, it is most frequently associated with the Driftless Area of the American Midwest. Because it describes a permanent physical state of the land, it is used as a technical classification rather than a general descriptive adjective.
