A collapse sinkhole in Knox County, where thicker residual soil covers limestone (highway right-of-way, I-75). Often, in heavily karst areas, there are no drainage features such as creeks and streams, since all of the drainage is beneath the ground surface.Large drainage systems in karst areas are likely to have both fluvial (surface) and karst (underground) drainage components. As stated in the introduction, the term karst describes a distinctive topography that indicates dissolution of underlying rocks by surface water or ground water. Water falls as rain or snow and soaks into the soil. They include areas underlain by Carboniferous limestone, notably the Mendips, parts of Wales, the Peak District, and the northern Pennines including the Yorkshire Dales.
