Ohio is a Midwestern state of the United States. "This slice of the mid-west contains a bit of everything American—part north-eastern and part southern, part urban and part rural, part hardscrabble poverty and part booming suburb," notes The Economist. It borders Pennsylvania on the east, Michigan in the northwest near Toledo, Ontario, Canada across Lake Erie to the north, Indiana to the west, Kentucky on the south, and West Virginia on the southeast.
Much of Ohio features glaciated plains, with an exceptionally flat area in the northwest being known as the Great Black Swamp. The rugged southeastern quadrant of Ohio, stretching in an outward bow-like arc along the Ohio River from the West Virginia Panhandle to the outskirts of Cincinnati, forms a distinct socio-economic unit. Significant rivers within the state include the Cuyahoga River, Great Miami River, Maumee River, Muskingum River, and Scioto River. Ohio has cold winters and warm, humid summers with an average temperature of 52°, Fahrenheit. Monthly average temperatures range from a high of 85.8 degrees to a low of 15.5 degrees.
