Jackson’s center stands about 160 ft above sea level. Within three miles the land runs from 90 ft to 300 ft, a difference of 210 ft: rolling country.
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 53×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Jackson reaches the Gulf of America by way of Thompson Creek and the Mississippi: about 290 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 92° in July; winter nights fall to about 42° in January. About 58 inches of rain fall in a normal year.
On November 14 Jackson normally reaches 71° and falls to 50°. The record high is 89°, in 1951; the record low 29°, in 1975. The most rain on this date, 1.47 in, fell in 1976.
