GeographyThe Chautauqua Drumlin Field encompasses an area of roughly 2,500 sq. km and spans from northwestern Pennsylvania into southwestern New York State, where more than 750 drumlins have been identified (Saha, 2010). The portion of Chautauqua Drumlin Field, as studied for this fieldwork, is located in northwestern Pennsylvania within the Northwestern Glaciated Allegheny Plateau physiographic province. This physiographic province contains numerous broad and rounded undulating hills of varying topographic relief, dissected by long smooth valleys; the majority of which trend northwest-to-southeast at approximately 150 degrees. Valley floors are typically comprised of wetlands, except in areas occupied by dwellings and infrastructure. Elevation ranges from 900 to 2,200 feet above sea level. Local drainage patterns are dendritic, and the many tributaries typically drain to the north towards Lake Erie.
