The Mississippi River acts as the central artery and state boundary between Illinois and Missouri on this survey, defining a landscape of complex waterways and river islands. The city of Quincy dominates the eastern bluffs, showing a dense urban grid that includes Quincy University and the Adams County Courthouse. The river’s braided character is evident in the numerous chutes and sloughs, such as Canton Chute and Crooked Slough, which separate significant landmasses like Quinsippi Island and Deadman Island.
