Keithsburg sits at the heart of this riverfront survey, positioned where Pope Creek meets the wide expanse of the Mississippi River. The town is flanked by a complex network of backwater channels and islands, including Blackhawk Island and Blackhawk Chute, illustrating the dynamic nature of the river border between Illinois and Iowa. To the north, the Mark Twain National Wildlife Refuge preserves the shoreline, while an Old Railroad Grade cutting through the landscape hints at the area's former transportation corridors.
