The Mississippi River and Rock River dominate this landscape, defining the borders between Illinois and Iowa as well as Rock Island and Henry Counties. The river-driven economy of the mid-20th century is evident through the placement of a gaging station and a substation near Rapids City. This survey reflects a well-established rural social structure, with a high density of country schools including Sycamore School, Leafy Bower School, and Zuma School scattered across the uplands of Coe and Zuma townships.
