Abstract
Several bedrock knobs less than a mile north of the Wisconsin glacial boundary in Fairfield County, Ohio, were mapped by previous workers as drift-free areas of resistant bedrock. Investigation of most of these knobs in the Amanda Quadrangle, Ohio, was made to determine the validity of these previous findings. With the exception of one knob, all of the knobs investigated contain glacial drift in the form of erratics and a weathered clayey soil developed on glacial till and/or loess.
