Land in the
Northern Shale Valleys setting.
Union township has 11.2 square miles of land in Union County. Its Census reference point is in Northern Shale Valleys, within Ridge and Valley.
Long, roughly parallel ridges and valleys follow folded and faulted rock layers. Limestone valleys, sandstone ridges and other geologic contrasts produce varied terrain and numerous regional springs and caves.

Union and Union County
Union is associated with Union 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 0.06 square miles of water within Union, or 0.5% of its total area. That share is close to Union County’s 0.6%. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Union township has 3.9 times the land area of nearby Winfield CDP (2.87 square miles). These areas describe boundaries, not comparable property prices.
