5.52 inches of rain fell in two days, the most for this week of the year since records began in 1944. The next wettest, 3.78 inches, fell in 1983.
Daviston’s center stands about 760 ft above sea level. Within three miles the land runs from 610 ft to 930 ft, a difference of 320 ft: rolling country. The highest named summit within 15 miles is White Oak Mountain, about 1,240 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Zana Granite (quartz-monzonite, granite), 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 31×. 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, phyllite. Age: Precambrian to Paleozoic. About 6 mi of the line.
Mica-schist. Age: Precambrian to Paleozoic. About 4 mi of the line.
Biotite-gneiss. Age: Precambrian to Paleozoic. About 2 mi of the line.
Amphibolite, schist. Age: Precambrian to Paleozoic. About 2 mi of the line.
Muscovite-schist. Age: Precambrian to Paleozoic. About 2 mi of the line.
Pyroxenite. 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 Daviston reaches Mobile Bay and the Gulf of America by way of Mill Creek, Hodnett Mill Creek, the Tallapoosa, the Alabama and the Mobile: about 470 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 Daviston; river miles along the main stem, rounded.
Daviston has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 30° in January. About 56 inches of rain fall in a normal year.
On November 14 Daviston normally reaches 66° and falls to 38°. The record high is 81°, in 1989; the record low 19°, in 2013. The most rain on this date, 2.20 in, fell in 1983.
Normals 1991–2020 and records since 1944 at Lafayette 2 W, 16 miles southeast. NOAA, through RCC-ACIS.
