In southwestern Ohio near Clough Creek, a tributary of the Little Miami River, two prehistoric sites together preserve evidence of Native settlement across more than one period. The Clough Creek site, about two acres in size, is believed to have been a large village, with surface finds and possible buried material indicating significant remains despite no formal excavation. Nearby Sand Ridge, long known for artifacts, was investigated in 1884 and yielded stone tools, pottery, projectile points, and animal bones. Evidence there points to seasonal occupation, strong reliance on fish, and a Fort Ancient village built over an earlier Late Woodland settlement.
