Abstract
During the Illinoian ice advance, large volumes of glacial outwash were carried east from the ice front near the present Madison Twp. Accumulation of outwash to an elevation of over 900 feet blocked the Teays valley forming a lake in Wakatomika Valley, a tributary to the north. This lake became filled with fine sediments and some spillover occurred at a low spot in the surrounding hills, creating an outlet 2.4 miles to the east of the former stream course. Wisconsin ice advances again blocked the westvvard flowing streams. Headward cutting by Wakatomika Creek pirated a stream in Jackson Twp. to the north. A heavy sediment load and high stream gradient eroded the Black Hand Sandstone comprising the valley walls to form rock terraces and speeding the down cutting of the outlet near Ashcraft Ford at an elevation of 760 feet. Outwash carried by the stream was deposited as terraces due to lower stream gradient and broader flood plain of the lower valley. Piracy of the stream to the east resulted in the deposition of a terrace which intermittently isolated the former stream valley, creating a backwater in which fine sediments accumulated. Postglacial stream action removed some of these deposits and alluvial deposits from the present valley floor.
