13° on Nov. 13, 2019, the coldest reading for this week of the year since 1891. Next is 14° in 1916.
Pinson’s center stands about 390 ft above sea level. Within three miles the land runs from 370 ft to 560 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Sand Mountain, about 740 ft, 15 miles east.
Under the town center the state geologic map shows Midway Group including Porters Creek Clay and Clayton Formation, from the Tertiary, 2.6 to 66 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay. Age: Tertiary, 2.6 to 66 million years old. About 13 mi of the line.
Sand. Age: Tertiary, 2.6 to 66 million years old. About 11 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Pinson reaches the Gulf of America by way of Bear Creek, the South Fork Forked Deer, the Forked Deer, the Obion and the Mississippi: about 920 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pinson; river miles along the main stem, rounded.
Pinson has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 27° in January. About 57 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Pinson normally reaches 62° and falls to 37°. The record high is 80°, in 1985; the record low 15°, in 2019. The most rain on this date, 4.15 in, fell in 1915.
Normals 1991–2020 and records since 1891 at Jackson Experiment Sta, 11 miles northwest. NOAA, through RCC-ACIS.
