Fountain Inn’s center stands about 860 ft above sea level. Within three miles the land runs from 720 ft to 900 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Roper Mountain, about 1,220 ft, 12 miles north-northwest.
Under the town center the state geologic map shows Gneiss of Laurens area (biotite-gneiss), from the Neoproterozoic to Cambrian, 487 to 1,000 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 50×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Paleozoic, 252 to 542 million years old. About 8 mi of the line.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 7 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 6 mi of the line.
Metagranite. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Gneiss. Age: Paleozoic, 252 to 542 million years old. About 1 mi of the line.

A raindrop that lands in Fountain Inn reaches the Atlantic Ocean by way of Wilson Creek, Durbin Creek, the Enoree, the Broad, the Congaree, the Santee and the South Santee: about 290 river miles.
Lake on the way: Lib Pines Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fountain Inn; river miles along the main stem, rounded.
