The Mississippi River forms the central artery of this region, separating Alexandria in Missouri from the city of Warsaw in Illinois. The map documents a complex aquatic landscape of side channels and wetlands, including Hemp Slough, Pickle House Slough, and Whitney Slough. Along the river’s main course, a chain of named features like Greys Island, Kamps-Stiens Island, and Willow Bar reveal the shifting hydrology of the border.
