The Mississippi River forms the central axis of this Quad-Cities survey, delineating the border between Iowa and Illinois. At the heart of the waterway lies the Rock Island Arsenal, a significant military installation containing the Rock Island Confederate Cem. The urban grid of Davenport and Bettendorf dominates the Iowa side, while Rock Island and Moline occupy the southern bank.
