The Pickensville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
12° on Nov. 13, 2019, the coldest reading for this week of the year since 1934. Next is 18° in 1963.
Pickensville’s center stands about 230 ft above sea level. Within three miles the land runs from 130 ft to 300 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows High terrace deposits (sand), from the Pleistocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 63×. 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. Age: Cretaceous, 66 to 145 million years old. About 7 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Chalk, clay. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Chalk. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.

A raindrop that lands in Pickensville reaches Mobile Bay and the Gulf of America by way of the Tombigbee and the Mobile: about 310 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pickensville; river miles along the main stem, rounded.
Pickensville has a cold desert climate. Summer afternoons average 91° in July; winter nights fall to about 33° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Pickensville normally reaches 66° and falls to 42°. The record high is 81°, in 1985; the record low 22°, in 1963. The most rain on this date, 2.20 in, fell in 1957.
