Abstract
The Laurentide Ice Sheet (LIS) expanded and retreated multiple times over North America during the Pleistocene Epoch (Figure 1; Dalton et al., 2022). As the ice sheet’s position changed, nearby environments responded, and their remaining sediments record these shifts (Benn and Evans, 2014). Although there are widespread sedimentary records from the most recent glacial episode (Wisconsinan Stade, ~75,000 - 11,000 years ago), evidence of older glaciations has been removed by more recent glacial events. Studying earlier glacial deposits provides important insights into the tempo and nature of environmental change driven by the shifting position of the ice sheet margin. Here we present a high-resolution record of sediment grain size distribution through a single sedimentary succession near Cincinnati, Ohio, that predates the Wisconsinan Stade.
