21° on Nov. 13, 2019, the coldest reading for this week of the year since 1893. Next is 22° in 1940.
Natchitoches’s center stands about 120 ft above sea level. Within three miles the land runs from 100 ft to 240 ft, a difference of 140 ft: gently rolling country.
The section below crosses 6 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 9 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million 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 Natchitoches reaches the Gulf of America by way of the Old, the Bayou Brevelle, the Cane, the Red River, the Atchafalaya and the Lower Atchafalaya: about 320 river miles.
130 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Natchitoches; river miles along the main stem, rounded.
Natchitoches has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 38° in January. About 55 inches of rain fall in a normal year.
On November 14 Natchitoches normally reaches 69° and falls to 45°. The record high is 86°, in 1955; the record low 25°, in 2019. The most rain on this date, 1.90 in, fell in 1998.
