West Mansfield’s center stands about 1,090 ft above sea level. Within three miles the land runs from 1,050 ft to 1,130 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is Campbell Hill, about 1,550 ft, 10 miles west-southwest.
Under the town center the state geologic map shows Tymochtee and Greenfield Formations, Undivided (dolostone), from the Silurian, 428 to 445 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 36×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in West Mansfield reaches the Gulf of America by way of Bokes Creek, the Scioto, the Ohio and the Mississippi: about 1,780 river miles.
970 miles of the trip are on the Mississippi.
