Kurt Shoemaker

About

Dr. Kurt Shoemaker is a Professor of Geology in the Department of Natural Sciences at Shawnee State University. Originally a magmatic geochemist (his teaching responsibilities include Mineralogy and Petrology), fate and opportunity have shifted his research focus to the evolution of the upper Ohio Valley before and during the Pleistocene Epoch (“Ice Age”). Shoemaker is the SSU Campus Representative for the Geological Society of America.

Lake Tight

Two million years ago, the northwest-flowing Teays River system drained much of the western slope of the southern Appalachians—and the Ohio River did not yet exist. During the Pleistocene (“Ice Age”), glacial ice dammed the Teays River near Chillicothe, Ohio, leading to the impoundment of Lake Tight. With a surface area of almost 10,000 square miles and depths locally exceeding 250 feet, Lake Tight contained a volume of water comparable to Lake Erie and occupied the incipient Ohio Valley for thousands of years. Ultimately the failure of a secondary ice dam near Ripley, Ohio, caused Lake Tight to drain rapidly, spilling over ridgelines, breaching drainage divides, and capturing and reversing segments of preexisting streams. This event created the modern Ohio River.

While the broad outline of this history has been understood for over 100 years, the details of the Teays-Tight-Ohio transition have not been examined in a comprehensive regional and temporal context. Shoemaker’s research is focused on three major questions: (1) How did the Teays River system evolve in the few million years preceding glacial advance, during the so-called Deep Stage? (2) How did the system respond as the Teays drainage transitioned into the early stages of impoundment of Lake Tight? (3) What geomorphic features formed as the consequence of the impoundment and outflow of Lake Tight?

SSU provides an ideal “base of operations” for these studies, as Portsmouth is situated in the deepest part of Lake Tight’s basin; is 40 miles south of the locus of the ice dam at Chillicothe; and is adjacent to the breached divide that once separated the Teays River from its major western tributary, the ancient Portsmouth River. Students working with Shoemaker have presented their research at regional and national meetings of the Geological Society of America.
