Indiana is a U.S. state in the Midwestern and Great Lakes regions of North America. Indiana is the 38th-largest by area and the 17th-most populous of the 50 United States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th U.S. state on December 11, 1816. Indiana borders Lake Michigan to the northwest, Michigan to the north, Ohio to the east, Kentucky to the south and southeast, and Illinois to the west.
The average altitude of Indiana is about 760 feet above sea level. The highest point in the state is Hoosier Hill in Wayne County at 1,257 feet above sea level. The lowest point at 320 feet above sea level is in Posey County, where the Wabash River meets the Ohio River. The resulting elevation span, 937 feet , is the narrowest of any non-coastal US state. Only 2,850 square miles have an altitude greater than 1,000 feet and this area is enclosed within 14 counties. About 4,700 square miles have an elevation of less than 500 feet , mostly concentrated along the Ohio and lower Wabash Valleys, from Tell City and Terre Haute to Evansville and Mount Vernon.
