13° on Nov. 15, 1969, the coldest reading for this week of the year since 1955. Next is 17° in 1963.
Conasauga’s center stands about 850 ft above sea level. Within three miles the land runs from 750 ft to 1,510 ft, a difference of 760 ft: hilly country. The highest named summit within 15 miles is Big Frog Mountain, about 4,190 ft, 11 miles east.
Under the town center the state geologic map shows Athens Shale, from the Ordovician, 445 to 487 million years old.
The section below crosses 9 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.
Shale. Age: Cambrian, 487 to 542 million years old. About 8 mi of the line.
Shale. Age: Precambrian. About 4 mi of the line.
Shale. Age: Precambrian. About 3 mi of the line.
Graywacke. Age: Precambrian. About 3 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Conasauga reaches Mobile Bay and the Gulf of America by way of the Conasauga, the Oostanaula, the Coosa, the Alabama and the Mobile: about 750 river miles.
Lake on the way: Lay 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 Conasauga; river miles along the main stem, rounded.
Conasauga has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 29° in January. About 58 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Conasauga normally reaches 62° and falls to 37°. The record high is 79°, in 1999; the record low 19°, in 2013. The most rain on this date, 1.22 in, fell in 2007.
Normals 1991–2020 and records since 1955 at Cleveland Filter Plant, 15 miles north-northwest. NOAA, through RCC-ACIS.
