West Union’s center stands about 480 ft above sea level. Within three miles the land runs from 440 ft to 570 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Ladd Hill, about 670 ft, 9 miles east-southeast.
Under the town center the state geologic map shows Bond Formation (shale, sandstone, limestone), from the Late Pennsylvanian, 304 to 307 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Pennsylvanian, 304 to 307 million years old. About 11 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 4 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.

A raindrop that lands in West Union reaches the Gulf of America by way of Mill Creek, Big Bayou, the Wabash River Old Channel, the Old Channel Wabash, the Ohio and the Mississippi: about 1,270 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of West Union; river miles along the main stem, rounded.
West Union has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 20° in January. About 46 inches of rain fall in a normal year.
On November 14 West Union normally reaches 54° and falls to 34°. The record high is 71°, in 1902; the record low 13°, in 2019. The most rain on this date, 1.00 in, fell in 2024.
