4.84 inches of rain fell in two days, the most for this week of the year since records began in 1904. The next wettest, 4.00 inches, fell in 2009.
Bowdon’s center stands about 1,100 ft above sea level. Within three miles the land runs from 930 ft to 1,140 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Turkey Heaven Mountain, about 1,730 ft, 12 miles west.
Under the town center the state geologic map shows Garnet Mica Schist (mica-schist), from the Precambrian to Paleozoic.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mica-schist, gneiss. Age: Precambrian to Paleozoic. About 8 mi of the line.
Schist. Age: Precambrian to Paleozoic. About 8 mi of the line.
Mica-schist. Age: Precambrian to Paleozoic. About 7 mi of the line.
Phyllite, quartzite. Age: Precambrian to Paleozoic. About 0.9 mi of the line.
Hornblende-gneiss, amphibolite. Age: Precambrian to Paleozoic. About 0.7 mi of the line.

A raindrop that lands in Bowdon reaches Mobile Bay and the Gulf of America by way of Indian Creek, the Little Tallapoosa, the Tallapoosa, the Alabama and the Mobile: about 560 river miles.
310 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bowdon; river miles along the main stem, rounded.
Bowdon has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 32° in January. About 54 inches of rain fall in a normal year.
On November 14 Bowdon normally reaches 64° and falls to 39°. The record high is 80°, in 1955; the record low 20°, in 2019. The most rain on this date, 1.71 in, fell in 1972.
Normals 1991–2020 and records since 1904 at Carrollton, 11 miles east-northeast, 100 ft lower. NOAA, through RCC-ACIS.
