23° on Nov. 12, 2011, the coldest reading for this week of the year since 1996. Next is 24° in 2019.
Notasulga’s center stands about 520 ft above sea level. Within three miles the land runs from 340 ft to 620 ft, a difference of 280 ft: rolling country.
Under the town center the state geologic map shows Tuscaloosa Group undifferentiated (sand, clay, gravel), from the Cretaceous, 66 to 145 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay, gravel. Age: Cretaceous, 66 to 145 million years old. About 7 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Amphibolite. Age: Precambrian to Paleozoic. About 3 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 3 mi of the line.
Muscovite-schist. Age: Precambrian to Paleozoic. About 2 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. 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. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Notasulga reaches Mobile Bay and the Gulf of America by way of Red Creek, Uphapee Creek, the Tallapoosa, the Alabama and the Mobile: about 420 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 Notasulga; river miles along the main stem, rounded.
Notasulga has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 35° in January. About 56 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1996 at Auburn No.2, 12 miles east-northeast. NOAA, through RCC-ACIS.
