Hardin, the seat of Calhoun County, serves as the primary anchor along the western bank of the Illinois River. Connected by the Page Bridge to East Hardin, the town is centered around the Calhoun County Courthouse and serves as a vital crossing point in a region defined by its complex river geography. The surrounding landscape is a mosaic of bottomlands and islands, including Hurricane Island and Diamond Island, interspersed with numerous oxbow lakes and sloughs like Horse Shoe Lake and Miller Slough.
