The city of Johnsonville is located only a few miles from The Johnsonville Impact Crater, a circular geophysical feature that represents an ancient impact crater, situated at the junction of Lynches River and the Pee Dee River in South Carolina. Snows Island, at that point, is believed to be the upthrust of the center after the impact. This eight-mile-wide crater is not well defined at the surface and was discovered by magnetic anomalies and supported by the study of well drilling cores. Supposed impact breccia was found in these cores.
