The confluence of the Mississippi River and the Iowa River dominates this landscape, where a complex network of chutes, sloughs, and islands defines the border between Illinois and Iowa. To the west, Toolesboro sits on higher ground above the river flats, while the settlement of New Boston occupies the eastern shore near Boston Bay. The river's dynamic nature is evident in the numerous named landforms within the channel, including Bogus Island, Turkey Island, and Jonas Johnson Island, which are separated by smaller waterways like Bogus Chute and Turkey Chute.
