The western part of the county consists largely of spread-out flood-prone farms with spotty marshes along the Wabash and White Rivers. There are rolling hills around Owensville, and large forest and marshland tracts lie near the Gibson Generating Station and the three river settlements of Crawleyville, East Mount Carmel, and Skelton. The northern part is near the White River and is more given to hills and forest. The eastern part contains many hills and is also dotted with strip pits and active coal mines. The southern part is more given to valley and marshland, drained by the Pigeon Creek which flows south through Evansville. The highest point on the terrain (640 feet/195 meters ASL) is a hill two miles (3.2 km) north of Princeton.
