The Rock River meanders across this corner of Illinois, defining the physical and historical boundary where Rock Island, Whiteside, and Henry counties converge. In the north, Hillsdale sits along the river's path, while the village of Joslin and the riverfront area of Shady Beach anchor the central portion of the map. The landscape is heavily influenced by the waterway, featuring prominent landforms like Kempster Island and Peterson Island, along with a complex network of wetlands such as Oxbow Slough, Big Slough, and Spade Slough.
