21° on Nov. 13, 2019, the coldest reading for this week of the year since 1871. Next is 23° in 1940.
Bossier City’s center stands about 160 ft above sea level. Within three miles the land runs from 160 ft to 240 ft, a difference of 80 ft: gently rolling country. The highest named summit within 15 miles is Giddens Hill, about 420 ft, 8 miles east-northeast.
Under the town center the state geologic map shows Natural Levees (silt, clay), from the Holocene, less than 12,000 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 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.
Silt, clay. Age: Holocene, less than 12,000 years old. About 10 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Sand, clay, lignite. Age: Paleocene, 56 to 66 million years old. About 4 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Clay, silt, sand. Age: Pleistocene, 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Bossier City reaches the Gulf of America by way of the Flat, Red Chute Bayou, Loggy Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 410 river miles.
230 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bossier City; river miles along the main stem, rounded.
Bossier City 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 Bossier City 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.
