About this map

The Mississippi River valley anchors this mid-1980s landscape, serving as both a state boundary and a corridor for the Chicago Milwaukee St Paul and Pacific railroad. Along its banks, the Upper Mississippi River Wild Life and Fish Refuge spans the river islands, while the sprawling Savanna Army Depot occupies the Illinois side. Settlement patterns in eastern Iowa reflect a mix of river-town commerce and inland agricultural centers, from the industrial presence of Dubuque to smaller villages like St Donatus and La Motte.

Subterranean features and unique geology are prominent, highlighted by Maquoketa Caves State Park and the historic lead-mining region near the Mines of Spain State Nature Preserve. Dozens of active and inactive Quarries and Gravel Pits are mapped throughout Jackson County, showing the continued importance of mineral extraction to the local economy. Waterways like the Maquoketa River and Tete des Morts Creek provide a detailed drainage network across the limestone-influenced terrain.
