8.33 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 4.05 inches, fell in 1921.
Du Quoin’s center stands about 470 ft above sea level. Within three miles the land runs from 400 ft to 490 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Shelburn-Patoka Formations undivided (shale, limestone), from the Late Pennsylvanian, 304 to 307 million years old.
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.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 24 mi of the line.

A raindrop that lands in Du Quoin reaches the Gulf of America by way of Blacksop Creek, Reese Creek, the Little Muddy, the Big Muddy and the Mississippi: about 1,130 river miles.

Du Quoin has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 24° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Du Quoin normally reaches 56° and falls to 36°. The record high is 80°, in 1955; the record low 10°, in 1986. The most rain on this date, 6.70 in, fell in 1993.
