THE SENECA LAND BRIEF
Land in the
Blufflands and Coulees setting.
Seneca town has 58.3 square miles of land in Crawford 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.

Seneca and Crawford County
Seneca is associated with Crawford 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.
Seneca by land and water
The Census records 6.85 square miles of water within Seneca, or 10.5% of its total area. It is 5.8 percentage points higher than the 4.7% recorded for Crawford County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Seneca town has 69.3 times the land area of nearby Seneca CDP (0.84 square miles). These areas describe boundaries, not comparable property prices.
