About this map

Cooperstown and the riverfront settlement of La Grange anchor this detailed study of Brown County’s eastern edge. The landscape is defined by the convergence of the La Moine River and the Illinois River, creating a complex network of wetlands and backwaters such as Hancock Slough, Twin Ponds, and the wide expanse of Meredosia Lake. The topography shifts from the flat river valley bottomlands of La Grange Island and Meredosia Island to the higher elevations of Spunky Ridge, where several small tributaries like Baehr Br and Little Cr have carved out the terrain.

Genealogists will find a high density of family and community burial grounds, including the Vandeventer Cem, Lavina Henry Cem, and Arnold Cem. Historically significant infrastructure is also marked, such as the Star Bridge crossing the La Moine River and the Lock & Dam RD leading toward the Illinois River channel. The map provides a clear picture of the modern rural road network, showing how historic farm-to-market routes like Co RD 1600 E interface with the natural drainage patterns of the Illinois River basin.
