The Serpent Mound disturbance, south-central Ohio
The Serpent Mound disturbance is located at the common boundaries of Adams, Pike, and Highland countiesin southcentral Ohio (Fig. 1). The locality lies on the eastern edge of the Interior Low Plateau province and just west of the Appalachian Plateau. Serpent Mound State Memorial, a prehistoric Indian site of the Adena culture, is situated on the west side of the disturbance above Ohio Brush Creek. Two paved highways serve the area; all other roads within the disturbance are gravel. Ohio 73 crosses the southwest part of the disturbance, providing access to the Serpent Mound State Memorial, and Ohio 41 passes through the east side of the disturbance (Fig. 2). Pertinent 7½-minute Quadrangles are the Byington and Sinking Spring sheets.Access to most geologic sites within the area is by foot. All land within the disturbance is privately owned, and permission must be gained to visit it. Landowners, however, understand the scientific significance of the area and have granted access graciously.
