Cache and Carry | Ohio History Connection

Between the 1840s and the 1920s and from the various excavations of Squier and Davis, Warren Moorehead and Henry Shetrone, upwards of 11,000 large, crudely flaked Hornstone bifaces or discs were recovered from a single deposit in Mound #2 at the Hopewell Earthworks in Ross County, Ohio. Considering that a single item could average a pound or more, the entire deposit might weigh in at greater than 6 tons! Whatever the motivation was to expend the energy needed to travel to the quarry area, extract the raw material and reduce it to disc form and transport it all several hundred miles back to the Hopewell site just to create a relatively small feature in a 110 acre earthwork complex can only be imagined.
