Small sinkhole ponds exist but few natural lakes; however, several large rivers have been dammed to create reservoirs. . A Karst topography displays a variety of large or small scale features both on the surface and beneath. The Appalachian Basin Geologic Mapping Project performs geologic mapping at local and regional scales, and geologic research in The Valley and Ridge and Appalachian Plateaus physiographic provinces. Exokarst landforms are well represented. The Mississippian System in Kentucky is represented by mostly marine sedimentary rocks which originally extended across the entire State. Moreover, silica-karst processes are active today in warm temperate, subtropical, and tropical areas in sandy substrates where groundwater levels are well below the ground surface and can cause subsidence or disrupt developing . It has perfect . It is suggested that there is a correlation between Paleo-Indian sites and their physical proximity to such karst features as sinkholes or sinks. The less pure limestone, siltstones, and shales of the Salem and Warsaw develop a thinner, brownish soil and are more commonly exposed .

A deep valley with steep to vertical walls; in karst frequently formed by a river rising on impervious rocks outside the karst area. Near-vertical joints and cracks are eroded downward by solution, leaving portions of a previously coherent rock mass separated from one another, resulting in tower karst. A feature described as an aven when seen from below may equally be described as shaft when seen from above, and the naming of such a feature commonly depends purely upon the direction of exploration. These include; laminar calcretes, pseudo-anticlines, small scale karst, and breccias.
