2015 Map of Green Island

About this map

The Mississippi River creates a complex network of backwaters and islands where the Maquoketa River and Apple River converge along the Illinois-Iowa border. This 2015 survey details the riverine landscape near Hanover, showing the numerous named sloughs and lakes that define the bottomlands, such as Crooked Slough and Fish Lake. On the higher ground east of the river, small settlements like Whitton and Reeceville are linked by a grid of rural roads, including W Depot Rd and Green Island Rd. The map preserves the location of historic burial grounds like Lost Mound Cem and Reeceville Cem, providing valuable spatial data for genealogists. The topography is marked by deeply incised valleys or hollows, such as Sugar Camp Hollow and Schlect Hollow, which drain the bluffs overlooking the river valley.
