1901 Map of Peosta

About this map

The Mississippi River creates a natural corridor through this landscape at the turn of the century, where the river valley meets the upland prairies of eastern Iowa. The city of Dubuque sits as a vital rail and river hub, connected to East Dubuque and served by multiple major lines including the Illinois Central and the Chicago Great Western. The map reveals a dense network of early settlements and rural post points, such as Key West, St Donatus, and Garry Owen, illustrating the era's agrarian settlement patterns before modern highway consolidation. Waterways like the North Fork Maquoketa River and Tete de Mort River carve through the terrain, dictating the placement of early centers like Washington Mills. This survey, compiled from work by Jno. H. Renshawe and his team, provides a detailed look at the township divisions and early railroad spurs that defined Dubuque and Jackson counties during this formative period.
