THE POTOSI LAND BRIEF
Land in the
Blufflands and Coulees setting.
Potosi town has 46.1 square miles of land in Grant County. Its Census reference point is in Blufflands and Coulees, within Driftless Area.
Deeply cut valleys divide a bedrock plateau with windblown soil on many uplands. Glaciers had less influence here than in neighboring regions, leaving a distinctly hilly landscape.

Potosi and Grant County
Potosi is associated with Grant County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Potosi by land and water
The Census records 10.5 square miles of water within Potosi, or 18.6% of its total area. It is 15.5 percentage points higher than the 3% recorded for Grant County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Potosi town has 27.8 times the land area of nearby Potosi village (1.66 square miles). These areas describe boundaries, not comparable property prices.
