Glacial Lake Agassiz Basin setting.
Union township has 35.9 square miles of land in Grand Forks County. Its Census reference point is in Glacial Lake Agassiz Basin, within Lake Agassiz Plain.
The former bed of glacial Lake Agassiz forms an exceptionally flat plain in the Red River valley. Thick lake sediments overlie older glacial deposits across this historic prairie landscape.

Union and Grand Forks County
Union is associated with Grand Forks 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.
Union by land and water
The Census records 0.02 square miles of water within Union, or 0.1% of its total area. It is 0.2 percentage points lower than the 0.2% recorded for Grand Forks County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Union township has 100% of the land area of nearby Morgan township (35.9 square miles). These areas describe boundaries, not comparable property prices.
