10° on Nov. 15, 1969, the coldest reading for this week of the year since 1872. Next is 13° in 1957.
Franklin’s center stands about 2,080 ft above sea level. Within three miles the land runs from 2,010 ft to 2,890 ft, a difference of 880 ft: hilly country. The highest named summit within 15 miles is Wine Spring Bald, about 5,460 ft, 11 miles west.
Under the town center the state geologic map shows Coweeta Group; Biotite Gneiss (biotite-gneiss, amphibolite), from the Mesoproterozoic to Neoproterozoic, 542 to 1,600 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss, amphibolite. Age: Mesoproterozoic to Neoproterozoic, 542 to 1,600 million years old. About 18 mi of the line.
Granodiorite, quartz-diorite. Age: Middle Devonian, 390 to 391 million years old. About 3 mi of the line.
Amphibolite. Age: Mesoproterozoic to Neoproterozoic, 542 to 1,600 million years old. About 1 mi of the line.
Gneiss, mica-schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 0.7 mi of the line.
Metadunite. Age: Neoproterozoic to Paleozoic, 252 to 1,000 million years old. About 0.3 mi of the line.
Metagraywacke. Age: Neoproterozoic, 542 to 1,000 million years old. About 0.3 mi of the line.

A raindrop that lands in Franklin reaches the Gulf of America by way of Crawford Branch, the Little Tennessee, the Tennessee, the Ohio and the Mississippi: about 1,720 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Franklin; river miles along the main stem, rounded.
Franklin has a humid subtropical climate. Summer afternoons average 84° in July; winter nights fall to about 26° in January. About 56 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Franklin normally reaches 60° and falls to 33°. The record high is 77°, in 1985; the record low 15°, in 2019. The most rain on this date, 1.18 in, fell in 1957.
