13° on Nov. 14, 1986, the coldest reading for this week of the year since 1891. Next is 13° in 2019.
Salt Rock’s center stands about 580 ft above sea level. Within three miles the land runs from 570 ft to 1,080 ft, a difference of 510 ft: hilly country. The highest named summit within 15 miles is Stowers Knob, about 1,280 ft, 11 miles southeast.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. 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, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 1 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 Salt Rock reaches the Gulf of America by way of the Guyandotte, the Ohio and the Mississippi: about 1,670 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 Salt Rock; river miles along the main stem, rounded.
Salt Rock has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 26° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Salt Rock normally reaches 57° and falls to 37°. The record high is 82°, in 1993; the record low 13°, in 1986. The most rain on this date, 1.51 in, fell in 2024.
