Abstract

ABSTRACT: The surficial geology of the Delta 7.5-minute series quadrangle, and sections of the adjacent quadrangles (ca. 54.5 km 2 ), was mapped to elucidate the deglacial history of the Huron–Erie Lake Plain in northwest Ohio. Five depositional environments were identified: alluvial, aeolian, glacial, glaciolacustrine and glaciofluvial. The depositional environments were mapped on a hillshaded, light detecting and ranging digital elevation model using a sediment-landform approach. Map interpretations were field tested with borings, shallow pits, electrical resistivity and ground-penetrating radar surveys. Four prominent strandlines of Ancestral Lake Erie trend NNE to SSW across the study area at 238, 231, 224 and 221 m above sea level and are comprised of offshore bars, possible beaches and spits recording littoral drift from the NNE. This study emphasizes the importance of large-scale mapping and provides a framework for subsequent research in the region.
