Darlington’s center stands about 910 ft above sea level. Within three miles the land runs from 880 ft to 1,280 ft, a difference of 400 ft: rolling country. The highest named summit within 15 miles is Big Knob, about 1,400 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Allegheny Formation (sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 31×. 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 14 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Shale, siltstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.

A raindrop that lands in Darlington reaches the Gulf of America by way of Dilworth Run, North Fork Little Beaver Creek, Little Beaver Creek, the Ohio and the Mississippi: about 1,930 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 Darlington; river miles along the main stem, rounded.
Darlington has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 21° in January. About 41 inches of rain fall in a normal year.
On November 14 Darlington normally reaches 51° and falls to 34°. The record high is 71°, in 1994; the record low 8°, in 1986. The most rain on this date, 0.89 in, fell in 1997.
