18° on Nov. 13, 2019, the coldest reading for this week of the year since 1972. Next is 23° in 1997.
Quitman’s center stands about 240 ft above sea level. Within three miles the land runs from 160 ft to 320 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Driskill Mountain, about 560 ft, 11 miles west-northwest.
Under the town center the state geologic map shows Cook Mountain Formation (clay, marl), from the Eocene, 34 to 56 million years old.
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 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.
Clay, marl. Age: Eocene, 34 to 56 million years old. About 10 mi of the line.
Clay, silt, sand. Age: Eocene, 34 to 56 million years old. About 8 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sand, clay. Age: Eocene, 34 to 56 million years old. About 0.8 mi of the line.

A raindrop that lands in Quitman reaches the Gulf of America by way of Cypress Bayou, the Dugdemona, the Little River, the Black River, the Red River, the Atchafalaya and the Lower Atchafalaya: about 390 river miles.
Lake on the way: Catahoula Lake.
100 miles of the trip are on the Atchafalaya.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Quitman; river miles along the main stem, rounded.
Quitman has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 36° in January. About 61 inches of rain fall in a normal year.
On November 14 Quitman normally reaches 68° and falls to 44°. The record high is 84°, in 1983; the record low 26°, in 2014. The most rain on this date, 1.43 in, fell in 1993.
Normals 1991–2020 and records since 1972 at Bienville 3 NE, 13 miles west. NOAA, through RCC-ACIS.
