About this map

The Mississippi River dominates this mid-1980s landscape, serving as a political and geographical divider between Iowa and Illinois. The riverfront is heavily managed, featuring the Upper Mississippi River Wild Life and Fish Refuge and the Savanna Army Depot along its eastern banks. Major hubs like Dubuque and Savanna anchor the river crossings, while the interior terrain is defined by dramatic elevations such as Table Mound and Pilot Knob.

Resource extraction and transportation networks are visible throughout the region, with numerous quarries and established rail lines including the Milwaukee Road and Chicago and North Western. Small rural settlements like St Donatus, Zwingle, and La Motte dot the Iowa side, while recreational and conservation areas such as Maquoketa Caves State Park and Mines of Spain State Nature Preserve highlight the region's diverse karst and riverine environments.
