Folsomville’s center stands about 460 ft above sea level. Within three miles the land runs from 390 ft to 560 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Coal Knobs, about 710 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Carbondale Group (shale, 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 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, sandstone. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.

A raindrop that lands in Folsomville reaches the Gulf of America by way of the Brushy Fork, Coles Creek, East Fork Little Pigeon Creek, the Ohio and the Mississippi: about 1,210 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 Folsomville; river miles along the main stem, rounded.
Folsomville has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 25° in January. A normal year brings about 11 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Folsomville normally reaches 57° and falls to 37°. The record high is 77°, in 2011; the record low 20°, in 2014. The most rain on this date, 1.85 in, fell in 1993.
