4.23 inches of rain fell in two days, the most for this week of the year since records began in 1937. The next wettest, 3.12 inches, fell in 2018.
Ball Ground’s center stands about 1,110 ft above sea level. Within three miles the land runs from 920 ft to 1,310 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Burnt Mountain, about 3,300 ft, 14 miles north.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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, metasiltstone. Age: Precambrian to Paleozoic. About 8 mi of the line.
Mica-schist, gneiss. Age: Precambrian to Paleozoic. About 7 mi of the line.
Mica-schist. Age: Precambrian to Paleozoic. About 4 mi of the line.
Mica-schist, amphibolite. Age: Precambrian to Paleozoic. About 2 mi of the line.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 2 mi of the line.
Biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Ball Ground reaches Mobile Bay and the Gulf of America by way of Long Swamp Creek, the Etowah, the Coosa, the Alabama and the Mobile: about 740 river miles.
Lakes on the way: Lay Lake and Allatoona Lake.
310 miles of the trip are on the Alabama.

Ball Ground has a humid subtropical climate. Summer afternoons average 85° in July; winter nights fall to about 31° in January. About 59 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Ball Ground normally reaches 59° and falls to 40°. The record high is 75°, in 1954; the record low 16°, in 2019. The most rain on this date, 1.59 in, fell in 1972.
