Tunnelton’s center stands about 1,860 ft above sea level. Within three miles the land runs from 1,440 ft to 2,450 ft, a difference of 1,010 ft: steep hill country. The highest named summit within 15 miles is Brushy Knobs, about 3,270 ft, 11 miles east-southeast.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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 Tunnelton reaches the Gulf of America by way of Pringle Run, the Cheat, the Monongahela, the Ohio and the Mississippi: about 2,080 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tunnelton; river miles along the main stem, rounded.
Tunnelton has a cold desert climate. Summer afternoons average 79° in July; winter nights fall to about 17° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Tunnelton normally reaches 49° and falls to 30°. The record high is 67°, in 1958; the record low 7°, in 2024. The most rain on this date, 0.81 in, fell in 1945.
