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.
Christopher’s center stands about 440 ft above sea level. Within three miles the land runs from 380 ft to 530 ft, a difference of 150 ft: gently rolling country. The highest named summit within 15 miles is Grammer Hill, about 590 ft, 5 miles north-northeast.
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.
The section below crosses 2 rock units mapped at the surface.

Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 19 mi of the line.
Shale, sandstone, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 5 mi of the line.

A raindrop that lands in Christopher reaches the Gulf of America by way of the Big Muddy and the Mississippi: about 1,140 river miles.

Christopher 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 Christopher 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.
Normals 1991–2020 and records since 1893 at Du Quoin 4 SE, 8 miles west. NOAA, through RCC-ACIS.
