Illinois Physical Map

Illinois is mostly glacial plain — its physical map shows the river systems, not mountains.

Rendered from SRTM 30m elevation data + Natural Earth rivers/lakes + US Census state boundary. Four versions below, all free.

Highest Point

Charles Mound

1,235 ft

Lowest Point

Mississippi River at Cairo

279 ft

Illinois physical map showing the Central Lowlands, the Driftless Area, and the Mississippi/Ohio River valleys, with major peaks and cities labeled. Topographic relief from NASA SRTM elevation data.

Illinois physical map for the classroom

Elevation in color with shaded relief, plus the surrounding states and water for context. The labeled version marks the capital, major cities and the highest point. The blank version leaves them off so students can label the map themselves.

Illinois relief wall art

Illinois on its own, with strong shaded relief and no labels. The dark version has the most contrast. The light version uses far less ink on a home printer.

The physical geography of Illinois

Most of Illinois is a flat to gently rolling plain left behind by glaciers. Two corners escaped the ice. The northwest corner is part of the hilly Driftless Area and holds Charles Mound, the highest point. The far south has the rugged Shawnee Hills. Rivers form most of the state’s borders: the Mississippi on the west, the Ohio on the south and the Wabash on the southeast. The Illinois River crosses the middle of the state, and Lake Michigan touches the northeast.

Built from real data, not stock images.

Every Illinois physical map on this page was rendered from NASA SRTM 30-meter elevation data, with hydrography from Natural Earth and the shoreline-clipped state outline from the US Census Bureau. Each map is colored over that state’s own elevation range, and the relief shading is exaggerated so gentle terrain still shows.
