Holly Springs’s center stands about 1,110 ft above sea level. Within three miles the land runs from 890 ft to 1,190 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is Pine Log Mountain, about 2,340 ft, 13 miles northwest.
Under the town center the state geologic map shows Biotitic Gneiss / Mica Schist/ Amphibolite (amphibolite, biotite-gneiss, mica-schist), from the Precambrian to Paleozoic.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss, mica-schist, amphibolite. Age: Precambrian to Paleozoic. About 5 mi of the line.
Hornblende-gneiss, amphibolite. Age: Precambrian to Paleozoic. About 4 mi of the line.
Mica-schist. Age: Precambrian to Paleozoic. About 3 mi of the line.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 3 mi of the line.
Gneiss, granite. Age: Precambrian to Paleozoic. About 2 mi of the line.
Quartzite, phyllite. Age: Precambrian to Paleozoic. 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. 6 smaller units along the line are not listed.

A raindrop that lands in Holly Springs reaches Mobile Bay and the Gulf of America by way of Toonigh Creek, the Etowah, the Coosa, the Alabama and the Mobile: about 710 river miles.
Lakes on the way: Lay Lake and Allatoona Lake.
310 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Holly Springs; river miles along the main stem, rounded.
Holly Springs has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 29° in January. About 52 inches of rain fall in a normal year.
On November 14 Holly Springs normally reaches 62° and falls to 38°. The record high is 78°, in 1964; the record low 18°, in 2019. The most rain on this date, 1.70 in, fell in 1972.
Normals 1991–2020 and records since 1946 at Allatoona Dam 2, 13 miles west, 140 ft lower. NOAA, through RCC-ACIS.
