21° on Nov. 13, 2019, the coldest reading for this week of the year since 1871. Next is 23° in 1940.
Stonewall’s center stands about 230 ft above sea level. Within three miles the land runs from 180 ft to 320 ft, a difference of 140 ft: gently rolling country.
Under the town center the state geologic map shows Wilcox Group (undifferentiated) (sand, clay, lignite), from the Paleocene, 56 to 66 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 64×. 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, lignite. Age: Paleocene, 56 to 66 million years old. About 15 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Silt, clay. Age: Holocene, less than 12,000 years old. About 2 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 Stonewall reaches the Gulf of America by way of Brushy Bayou, Rambin Bayou, the Sampson Channel, the Bayou Pierre, the Red River, the Atchafalaya and the Lower Atchafalaya: about 390 river miles.
Lake on the way: Clear Lake One.
170 miles of the trip are on the Red River.
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 95° in August; winter nights fall to about 37° in January. About 51 inches of rain fall in a normal year.
On November 14 Stonewall normally reaches 68° and falls to 46°. The record high is 85°, in 1989; the record low 24°, in 1940. The most rain on this date, 2.67 in, fell in 1993.
