2016 Map of Potosi

About this map

The rugged driftless topography of Grant County meets the wide expanse of the Mississippi River in this 2016 record of the Wisconsin-Iowa border. The settlement pattern follows the intricate network of coulees and hollows, where small communities like Potosi, Tennyson, and British Hollow are positioned along the winding valley floors. This area's long mining and brewing history is reflected in names like Brewery Hollow Rd and British Hollow, while the agricultural character is maintained across the high ridges. Genealogical landmarks are prominent, including Saint Thomas Cem, British Hollow Cem, and the Van Buren Cem. The map captures the significant transition from the upland bluffs down to the river bottoms at Island Number Two Hundred Eleven, where the state line divides the channel between Wisconsin and Iowa.
