This sandstone outcrop in Knox County is inferred to be part of the Logan Formation, a Lower Mississippian siliciclastics-dominated succession in eastern Ohio. It represents a relatively shallow marine deposit. Observed fossils at this site include brachiopods, crinoids, gastropods, and bellerophontids.
