Southern Indiana is a geographic and cultural region that generally comprises the southern third of theU.S. state ofIndiana and borders the states ofIllinois to the west,Kentucky to the south, andOhio to the east. Spanning the state's southernmost 33 counties, its main population centers includeSouthwestern Indiana (anchored by the city ofEvansville), theLouisville metropolitan area (south), and theCincinnati metropolitan area (southeast). The region's history and geography have led to a blending ofSouthern andMidwestern cultures, distinct from the rest of the state. It is often considered to be part of theUpland South and the Southern influenced Lower Midwest.[1]
TheWabash forms the region's western boundary andOhio forms the region's entire southern and the majority of its eastern boundary. Elevation ranges from around 360 feet (110 m)above mean sea level at the rivers' confluence to 1,060 feet (320 m) at the highest point in theKnobstone Escarpment. Southern Indiana's topography is considerably more varied than Central andNorthern Indiana, including large tracts of forest, rolling hills, andkarst caves. The region is also home to the oldest exposedDevonian fossil beds in the world at theFalls of the Ohio National Wildlife Conservation Area. Situated in theWabash Valley seismic zone,Southwestern Indiana is at elevated risk for earthquakes.
