1957 Map of Potosi

About this map

The rugged bluff country of Grant County meets the winding waters of the Mississippi River in this detailed look at a historic lead-mining region. Significant mining activity is evidenced by a Mine and Quarry, while the town of Potosi stretches through narrow valleys toward its river landing at Potosi Station. This 1957 survey, updated with 1972 revisions, reveals the complex relationship between the steep driftless topography of Hog Hollow and Yankee Hollow and the vital transport corridors of the Burlington Northern and Chicago Milwaukee St Paul and Pacific railroads. The map captures the interface between industrial development and conservation within the Upper Mississippi River Wildlife and Fish Refuge, which encompasses Island 211 and Island 212. Local history and genealogy are well-represented by several burial grounds, including St Thomas Cem, Van Buren Cem, and Osceola Cem, alongside rural landmarks like the Rigsby Sch.
