Ph.D. 地质学,2004
论文The Tectonomagmatic Evolution of the Late Cenozoic Owyhee Plateau, Northwestern United States

B.S. 地质学,1995年


Dr. Shoemaker is a Professor of 地质 in the Department of 自然科学 at 肖尼 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 俄亥俄州 Valley before and during the Pleistocene Epoch (“Ice Age”). Shoemaker is the SSU Campus Representative for the 美国地质学会.

两百万年前, the northwest-flowing Teays River system drained much of the western slope of the southern Appalachians—and the 俄亥俄州 River did not yet exist. 更新世时期(“冰河时期”), glacial ice dammed the Teays River near Chillicothe, 俄亥俄州, 导致塞湖蓄水. 表面积几乎是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 俄亥俄州 Valley for thousands of years. Ultimately the failure of a secondary ice dam near Ripley, 俄亥俄州, 导致塞湖迅速排水, spilling over ridgelines, breaching drainage divides, and capturing and reversing segments of preexisting streams. 这一事件造就了今天的俄亥俄河.

While the broad outline of this history has been understood for over 100 years, the details of the Teays-Tight-俄亥俄州 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, 在所谓的深度阶段? (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. 学生 working with Shoemaker have presented their research at regional and national meetings of the 美国地质学会.
