and it forms thick reddish-brown soils and minor karst features. resulting in the characteristic "karst" topography with many caves, underground streams, and sinkholes. Geologists also refer to this time as the Pleistocene, a formal period of geologic time that began 2 million years ago and technically ended 10,000 years ago. Although karst features are not as numerous or well developed as in the Mississippian Plateaus of the Mammoth Cave area, some springs were the sites of early settlements such as Georgetown, Harrodsburg, and Lexington.
