About this map

Hannibal sits as the primary urban center on this Missouri riverfront, where the Burlington Northern and Norfolk and Western railroads converge to cross the Mississippi River. This era shows a landscape deeply tied to its natural limestone features and literary legacy, notably marked by Mark Twain Cave, Cameron Cave, and the landmark Cardiff Hill. Beyond the city limits, the terrain transitions into the wooded hills of Saverton township, punctuated by numerous industrial operations including an extensive network of quarries and mines.

Rural life is anchored by family and community sites such as Antioch Ch, Mt Olivet Cem, and Pettibone Sch. Across the river, the vast Levee system protects low-lying Illinois settlements like East Hannibal and Shepherd from the seasonal shifts of the Sny Slough. The intricate river geography, featuring Tower Island and Shuck Island, illustrates the complex hydrological management required for 1970s navigation and flood control.
