About this map

The Mississippi River creates a complex landscape of backwater sloughs and islands along the border of Iowa and Illinois. This 2010 survey shows the river's dynamic nature, with features like Crooked Slough, Morse Island, and Kennedy Bar shaping the navigational channel. On the Iowa side, the small settlement of Green Island is a focal point, situated near the Maquoketa River confluence. The terrain is marked by numerous hollows, including Sugar Camp Hollow and Mooney Hollow, which drain the bluffs toward the river valley.

Local history is preserved in the location of the Green Island Post Office and rural burial grounds such as Lost Mound Cemetery and Reeceville Cemetery. The Illinois side features the prominent Lost Mound and the community of Whitton. The abundance of named lakes like Snider Lake, Fish Lake, and Goose Lake illustrates the intricate wetland ecosystem that defines this stretch of the Mississippi flyway.
