82° on Nov. 17, 1958, the hottest reading for this week of the year since 1922. Next is 79° in 1993.
Mannington’s center stands about 1,030 ft above sea level. Within three miles the land runs from 980 ft to 1,540 ft, a difference of 560 ft: hilly country. The highest named summit within 15 miles is Catherines Knob, about 1,710 ft, 9 miles northeast.
Under the town center the state geologic map shows Dunkard Group (sandstone, siltstone, shale), from the Carboniferous to Permian, 252 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 28×. 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, siltstone, shale. Age: Carboniferous to Permian, 252 to 324 million years old. About 22 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Mannington reaches the Gulf of America by way of Buffalo Creek, the Monongahela, the Ohio and the Mississippi: about 2,090 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 Mannington; river miles along the main stem, rounded.
Mannington has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 24° in January. About 45 inches of rain fall in a normal year.
On November 14 Mannington normally reaches 56° and falls to 36°. The record high is 77°, in 1955; the record low 12°, in 1986. The most rain on this date, 1.43 in, fell in 2007.
