THE UNION LAND BRIEF
Land in the
Pre-Wisconsinan Drift Plains setting.
Union township has 20.9 square miles of land in Clark County. Its Census reference point is in Pre-Wisconsinan Drift Plains, within Eastern Corn Belt Plains.
Rolling glacial till plains are interrupted by end moraines and areas of older, more dissected deposits. The historical landscape had more tree cover than the Central Corn Belt to the west.

Union and Clark County
Union is associated with Clark 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 0.22 square miles of water within Union, or 1% of its total area. That share is close to Clark County’s 1.1%. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Union township has 8 times the land area of nearby Memphis CDP (2.6 square miles). These areas describe boundaries, not comparable property prices.
