Ash by land and water
The Census records 0.12 square miles of water within Ash, or 0.3% of its total area. That share is close to Pennington County’s 0.3%. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Ash township has 1.1 times the land area of nearby Sunnyside township (38.9 square miles). These areas describe boundaries, not comparable property prices.
