−15° on Nov. 12, 2014, the coldest reading for this week of the year since 1971. Next is −13° in 1986.
Fairburn’s center stands about 3,300 ft above sea level. Within three miles the land runs from 3,200 ft to 3,660 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Mount Coolidge, about 6,000 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Alluvium (coarse-detrital, fine-detrital), from the Quaternary, less than 2.6 million 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 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, siltstone, sandstone. Age: Eocene to Oligocene, 23 to 56 million years old. About 6 mi of the line.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 6 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Quartzite, schist. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 3 mi of the line.
Coarse-detrital, clay. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Claystone, conglomerate, sandstone. Age: Early Cretaceous, 100 to 145 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Fairburn reaches the Gulf of America by way of French Creek, the Cheyenne, the Missouri and the Mississippi: about 2,510 river miles.
Lakes on the way: Lake Oahe, Lake Sharpe, Lake Francis Case and Lewis and Clark Lake.
1,170 miles of the trip are on the Mississippi.

Fairburn has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 11° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 18 inches of water.
On November 14 Fairburn normally reaches 50° and falls to 21°. The record high is 74°, in 2025; the record low −11°, in 2014. The most rain on this date, 0.06 in, fell in 1985.
