Geography of Indiana
Glaciers flattened the northern two-thirds of Indiana during the Ice Ages, leaving level farmland of corn and soybeans. The southern third escaped the last ice sheets and is hilly, wooded and riddled with limestone caves.
Northern Indiana
- Calumet Region: the industrial northwest corner on Lake Michigan, with Gary, Hammond and East Chicago, part of the Chicago metro area.
- Indiana Dunes: sand dunes, beaches and wetlands along the lakeshore between Gary and Michigan City, protected since 2019 as Indiana Dunes National Park.
- Michiana: South Bend, home of the University of Notre Dame, and Elkhart, a center of RV manufacturing, near the Michigan line.
- Northeast Indiana: Fort Wayne, where the St. Joseph and St. Marys rivers join to form the Maumee River, plus a cluster of small glacial lakes.
Central Indiana
The Tipton Till Plain covers the middle of the state. Indianapolis sits on the White River, surrounded by fast-growing Hamilton County suburbs (Carmel, Fishers, Noblesville) and older industrial cities such as Anderson, Muncie and Kokomo. Purdue University is in West Lafayette, across the Wabash River from Lafayette. The capital moved from Corydon to Indianapolis in 1825.
Southern Indiana
- Hill country: forested ridges in Brown County and the Hoosier National Forest, and Bloomington, home of Indiana University.
- Limestone belt: quarries around Bloomington and Bedford supply building stone, and the karst landscape has caves such as Marengo and Wyandotte.
- Ohio River valley: Evansville in the southwest, historic Madison, and New Albany, Jeffersonville and Clarksville across the river from Louisville.
- Wabash Valley: the Wabash River crosses the state and forms the southern part of the border with Illinois, passing Terre Haute and Vincennes, Indiana’s oldest town.
- Lincoln country: Lincoln Boyhood National Memorial in Spencer County, where Abraham Lincoln lived from age 7 to 21.
Hoosier Hill, the highest point at 1,257 ft, is a low rise on farmland in Wayne County near the Ohio line, north of Richmond.
