Ohio's topography ranges from flat, glaciated plains to dramatic, rugged ravines. The highest point in the state is Campbell Hill, reaching 1,550 feet (472 meters) above sea level in Logan County, which is situated gently on the rolling plains. The lowest point is located in the extreme southwestern corner of the state along the Ohio River, at 455 feet (139 meters) above sea level.
The eastern Appalachian Plateau provides Ohio's most dramatic topography. The Hocking Hills region in the southeast is renowned for its deep, moss-covered gorges, sheer rock walls, recess caves, and waterfalls carved out of Black Hand Sandstone. Meanwhile, the northern coastal area consists of miles of Lake Erie shoreline, featuring low cliffs, beaches, and marshlands. The central and western parts of the state are dominated by gently rolling hills and broad, flat floodplains created by rivers like the Scioto, Miami, and Muskingum.
