Sentinel and Golden Valley County
Sentinel is associated with Golden Valley 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.
Sentinel by land and water
The Census records 0.29 square miles of water within Sentinel, or 0.2% of its total area. That share is close to Golden Valley County’s 0.2%. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Sentinel township has 139.4 times the land area of nearby Sentinel Butte city (1.03 square miles). These areas describe boundaries, not comparable property prices.
