Deposits in gravel pit along valley of Mill Creek in Garfield Heights, OH, are unique because no similar deposits have been found in northeastern OH. Here late Wisconsinan sediments overlie a diamicton interpreted as early Wisconsinan accretion gley and Garfield Heights Till because of its stratigraphic placement above a possible Sangamonian soil. The diamicton is yellowish-brown to greenish-gray and underlies a lower loess. Its structure ranges from platy to blocky to massive, and its matrix texture varies among and within measured sections. Pebble bands are common and joints are coated with iron and manganese oxides. This diamicton has been interpreted by several previous workers as an accretion gley and/or till. The unweathered part of the diamicton has been interpreted as a subglacial till on the basis of its fissility, high density, pebble lithology, and heavy-mineral composition, and has been called the Garfield Heights Till. Dreimanis (this volume) correlates the Bradtville Till on the north shore of Lake Erie to the Garfield Heights. Currently, then, the Garfield Heights is assigned to the Illinoian.
