2018 Map of Green Island

About this map

Green Island lies at the complex confluence of the Mississippi River, the Maquoketa River, and the Apple River, a landscape defined by an intricate network of sloughs and backwaters. This 2018 survey detail shows the persistent settlement patterns along the river bluffs and valleys, from the town of Hanover in the north to the smaller communities of Reeceville and Twin Springs in the south. The terrain is marked by numerous named hollows like Schlect Hollow and Friday Hollow, which dictate the local road network. Local heritage is preserved at sites such as Reeceville Cem and Lost Mound Cem, while the river itself is dotted with named landforms including Morse Island, Kennedy Bar, and Railroad Island. The map illustrates the geographical boundary where Illinois and Iowa meet, showing how the shifting waterways and islands like Island Number 254 have historically shaped the regional borders.
