83° on Nov. 14, 1955, the hottest reading for this week of the year since 1894. Next is 81° in 1924.
Hartselle’s center stands about 670 ft above sea level. Within three miles the land runs from 570 ft to 760 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Peck Mountain, about 1,200 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Hartselle Sandstone, from the Carboniferous, 324 to 359 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 32×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 15 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Limestone, shale. Age: Carboniferous, 324 to 359 million years old. About 0.5 mi of the line.

A raindrop that lands in Hartselle reaches the Gulf of America by way of Shoal Creek, Flint Creek, the Tennessee, the Ohio and the Mississippi: about 1,350 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical) and Pickwick 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 Hartselle; river miles along the main stem, rounded.
Hartselle has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 33° in January. About 54 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Hartselle normally reaches 64° and falls to 41°. The record high is 83°, in 1955; the record low 18°, in 1911. The most rain on this date, 2.21 in, fell in 1993.
