Before the glacial invasion of Pleistocene time, the streams of the present Ohio Basin flowed generally northwestward and were carried by the Teays River and its tributaries. The Teays River rose in the Piedmont Plateau of Virginia and North Carolina and flowed northwestward across West Virginia, Ohio, Indiana, and Illinois to the ancestral Mississippi River. This system of drainage was brought to a close by the advance of Pleistocene glaciers, which filled the valleys and formed new drainage patterns. The buried valleys of Pleasant Township, Madison County, Ohio, have been mapped for this report from well records. The bedrock of Madison County consists mainly of limestone and dolomite strata of Silurian and Devonian ages. These are generally dependable sources of water supply for community use, farms and suburban homes. Sand and gravel beds which underlie or are interbedded in the glacial till are also sources of water, along with sand and gravel beds associated with the Darby Creek and Deer Creek valleys.
