7° on Nov. 16, 1933, the coldest reading for this week of the year since 1872. Next is 10° in 1967.
Nemacolin’s center stands about 1,190 ft above sea level. Within three miles the land runs from 760 ft to 1,260 ft, a difference of 500 ft: hilly country. The highest named summit within 15 miles is Devies Mountain, about 2,780 ft, 15 miles southeast.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. 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, shale. Age: Carboniferous to Permian, 252 to 324 million years old. About 7 mi of the line.
Limestone, shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Sandstone, shale. Age: Permian, 252 to 299 million years old. About 5 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.7 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Nemacolin reaches the Gulf of America by way of the Monongahela, the Ohio and the Mississippi: about 2,020 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 Nemacolin; river miles along the main stem, rounded.
Nemacolin has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 24° in January. About 43 inches of rain fall in a normal year.
On November 14 Nemacolin normally reaches 55° and falls to 36°. The record high is 78°, in 1993; the record low 10°, in 1986. The most rain on this date, 0.91 in, fell in 1995.
