18° on Nov. 13, 2019, the coldest reading for this week of the year since 1895. Next is 19° in 1940.
Adamsville’s center stands about 580 ft above sea level. Within three miles the land runs from 390 ft to 740 ft, a difference of 350 ft: rolling country. The highest named summit within 15 miles is Little Shades Mountain, about 860 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Pottsville Formation (upper part) (shale, siltstone, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. 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, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Dolostone, chert. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Limestone, shale. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Sandstone. Age: Silurian, 422 to 445 million years old. About 0.6 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Adamsville reaches Mobile Bay and the Gulf of America by way of Cane Creek, Village Creek, the Locust Fork, the Black Warrior, the Tombigbee and the Mobile: about 420 river miles.
170 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Adamsville; river miles along the main stem, rounded.
Adamsville has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 35° in January. About 57 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Adamsville normally reaches 65° and falls to 43°. The record high is 82°, in 1955; the record low 23°, in 2014. The most rain on this date, 4.43 in, fell in 1929.
