Ohio

Ohio Geography

Scattered sand dunes are found across Ohio's Lake Erie shoreline. East of Cleveland, slightly elevated clay bluffs front the lake.

The Bass Islands, a group of small, mostly limestone islands, are located off the state's northern coastline. Kelleys Island, the largest fresh water American island in Lake Erie, is about 5 miles off the coast.

To the southwest of Sandusky the fertile and mostly low-lying landscape, punctuated by a few isolated hills, continues on into Indiana and beyond.

The rolling hills and valleys of the Allegheny Plateau stretch across the far-south as well as the eastern-half of Ohio. Another hilly area in east-central Ohio contains the state's highest point; Campbell Hill, at 1,549 ft.

With over 300 miles of Lake Erie shoreline and thousands of miles of rivers, Ohio is truly defined by these valuable, and useful waterways.

The most significant river is the Ohio, as it forms it entire southern border, and much of its eastern border.

Other major rivers of note include the Cuyahoga, Miami, Maumee, Muskingum and Scioto.
