The Mississippi River forms a complex boundary between Illinois and Iowa on this survey, where the river's dynamic nature is evidenced by the Old Channel and various backwaters like Jordan Chute and Shokokon Slough. The landscape is dominated by the floodplains of Gladstone, Carman, and Stronghurst, where a network of rural schools—including Merry Dell Sch and Kirby Sch—served the agricultural community.
