GEOLOGY and LANDFORMS

Four geologic provinces running in a generally east-west direction shape the Lower Delaware River corridor's varied landscapes. The topography of the northern end of the corridor is broken by rocky and mountainous terrain. The middle river corridor is comprised of hills and clay soils, which contrast markedly with the southernmost province - the flat, marshy coastal plain.
