85° on Nov. 13, 1964, the hottest reading for this week of the year since 1889. Next is 84° in 1921.
Stonewall’s center stands about 250 ft above sea level. Within three miles the land runs from 220 ft to 410 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Tunnel Hill, about 540 ft, 14 miles north.
Under the town center the state geologic map shows Kosciusko formation (sand, clay), from the Eocene, 34 to 56 million years old.
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 58×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 11 mi of the line.
Clay, sand. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Clay. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Clay, sand. Age: Eocene, 34 to 56 million years old. About 2 mi of the line.
Claystone, clay. Age: Eocene, 34 to 56 million years old. About 1 mi of the line.
Marl, sand. Age: Eocene, 34 to 56 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Stonewall reaches the Gulf of America by way of Bostic Branch, the Chickasawhay, the Pascagoula and the West Pascagoula: about 230 river miles.
150 miles of the trip are on the Chickasawhay.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stonewall; river miles along the main stem, rounded.
Stonewall has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 36° in January. About 57 inches of rain fall in a normal year.
On November 14 Stonewall normally reaches 69° and falls to 43°. The record high is 84°, in 1921; the record low 21°, in 1963. The most rain on this date, 2.07 in, fell in 1929.
Normals 1991–2020 and records since 1889 from the Meridian Area threaded record (Meridian Key Field, 14 miles north). NOAA, through RCC-ACIS.
