Jackson’s center stands about 410 ft above sea level. Within three miles the land runs from 340 ft to 550 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Norton Hill, about 610 ft, 6 miles south-southeast.
Under the town center the state geologic map shows Claiborne and Wilcox Formation (sand), 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 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. Age: Tertiary, 2.6 to 66 million years old. About 18 mi of the line.
Silt. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Jackson reaches the Gulf of America by way of the South Fork Forked Deer, the Forked Deer, the Obion and the Mississippi: about 910 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jackson; river miles along the main stem, rounded.
Jackson 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 Jackson 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, here. NOAA, through RCC-ACIS.
