22° on Nov. 15, 1963, the coldest reading for this week of the year since 1956. Next is 24° in 1969.
Cogdell’s center stands about 180 ft above sea level. Within three miles the land runs from 170 ft to 230 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Pleistocene-Pliocene sands and gravels (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 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, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 21 mi of the line.
Fine-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 1 mi of the line.

A raindrop that lands in Cogdell reaches the Gulf of America by way of the Suwannee: about 280 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cogdell; river miles along the main stem, rounded.
Cogdell has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 37° in January. About 49 inches of rain fall in a normal year.
On November 14 Cogdell normally reaches 71° and falls to 45°. The record high is 89°, in 1956; the record low 26°, in 1963. The most rain on this date, 1.41 in, fell in 1972.
