1984 Map of Dubuque South

About this map

The Upper Mississippi River Wild Life and Fish Refuge dominates the eastern corridor of this region, where the river carves through a landscape of high bluffs and numerous islands. This 1984 survey documents a complex network of midwestern river-town economies and conservation areas, including the Mines of Spain State Nature Preserve south of Dubuque. The map illustrates the strategic importance of the Mississippi waterway, anchored by Lock and Dam No 12 at Bellevue and the massive Savanna Army Depot on the Illinois bank. Inland, the topography transitions to the rolling agricultural lands of Jackson and Dubuque Counties, where small settlements like Garry Owen and St Donatus are connected by a web of early roads and rail lines, including the Chicago Milwaukee St Paul and Pacific Railroad. Geologists and local historians will find significant detail in the numerous quarries and distinctive limestone features preserved at Maquoketa Caves State Park.
