Roy T. Dawson, driller, and William R. Dunfee, drilling assistant, with the Ohio Geological Survey's Mobile B-61 Pacemaker core rig drilling the first of 16 core holes for the Superconducting Super Collider (SSC) project. Drilling was done in the Columbus Limestone of the Devonian Geologic Period at the Penry Stone Company, Inc., quarry south of Radnor, Delaware County, Ohio. The SSC was proposed by the United States Department of Energy as the largest, most powerful particle accelerator ever built. It would enable physicists to shatter protons into their constituent subatomic particles in order to study the basic structure of the atom. At least 20 states were expected to submit proposals by August 1987 to be awarded the SSC project location. A detailed geologic report was needed for the proposed area in Ohio, which was north of Columbus in Delaware, Marion, Morrow and Union counties. Ohio Geological Survey geologists mapped and described surface exposures of bedrock and glacial deposits in the SSC area to prepare top-of-rock and drift-thickness maps. The 16 core holes were drilled using the Survey's two core-drilling rigs. Each hole was approximately 250 feet deep. A similar number of holes were drilled with the Survey's auger rig. The image was taken by Michael C. Hansen in March 1987 based on information from Ohio Geological Survey Core Record File No. 2630.
