West Logan’s center stands about 1,060 ft above sea level. Within three miles the land runs from 660 ft to 1,950 ft, a difference of 1,290 ft: steep hill country. The highest named summit within 15 miles is Kelly Mountain, about 2,180 ft, 12 miles east-southeast.
Under the town center the state geologic map shows Kanawha Formation (sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 23 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 0.7 mi of the line.

A raindrop that lands in West Logan reaches the Gulf of America by way of the Guyandotte, the Ohio and the Mississippi: about 1,720 river miles.
970 miles of the trip are on the Mississippi.
