15° on Nov. 15, 1969, the coldest reading for this week of the year since 1946. Next is 16° in 2025.
Canton’s center stands about 960 ft above sea level. Within three miles the land runs from 860 ft to 1,250 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Sharp Mountain, about 2,340 ft, 14 miles north.
Under the town center the state geologic map shows Mica Schist/ Metasiltstone (mica-schist, metasiltstone), from the Precambrian to Paleozoic.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Hornblende-gneiss, amphibolite. Age: Precambrian to Paleozoic. About 5 mi of the line.
Mica-schist, metasiltstone. Age: Precambrian to Paleozoic. About 5 mi of the line.
Mica-schist. Age: Precambrian to Paleozoic. About 3 mi of the line.
Quartzite, phyllite. Age: Precambrian to Paleozoic. About 2 mi of the line.
Metagraywacke, mica-schist, quartzite. 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.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Canton reaches Mobile Bay and the Gulf of America by way of 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 Canton; river miles along the main stem, rounded.
Canton 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 Canton 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, 15 miles west-southwest. NOAA, through RCC-ACIS.
