Vertical Variability and Lateral Distribution of Late Wisconsinan Sediments Parallel to theAxis of the Buried Valley of Mud Brook North of Akron, Summit County, Ohio

Author Institution: Department of Geology & Environmental Science, University of AkronThe buried valley of Mud Brook in northern Summit County, OH, contains sediments associated with the late Wisconsinan glaciation. The vertical variability and lateral distribution of these sediments can be ascertained from information derived from logs from highway borings and water wells along a 15-km north-south transect parallel to the axis of the buried valley. Textural, carbonate, clay mineral, and lithologic analyses of samples from roadcuts, geological borings, and some highway department borings provide additional information to assign lithofacies units to specific glaciations. Cross sections show that nearly similar depositional environments existed before each late Wisconsinan glacial advance. The proglacial sediments consist of outwash and lacustrine deposits overridden by ice that deposited an overlying till. Sediments associated with the Lavery and Hiram advances overlie a Kent-aged kame plateau within the Summit County Morainic Complex at the southern end of the study area. Farther north meltwater accumulated and drowned ground moraine to form post-glacial lakes that were eventually drained as the drainage network of Mud Brook became better integrated
