5.28 inches of rain fell in two days, the most for this week of the year since records began in 1924. The next wettest, 3.74 inches, fell in 2015.
Gleason’s center stands about 410 ft above sea level. Within three miles the land runs from 350 ft to 500 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Quaternary, less than 2.6 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.
Silt. Age: Quaternary, less than 2.6 million years old. About 16 mi of the line.
Sand. Age: Tertiary, 2.6 to 66 million years old. About 6 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 Gleason reaches the Gulf of America by way of Morris Branch, the Middle Fork Obion, the Obion and the Mississippi: about 940 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gleason; river miles along the main stem, rounded.
Gleason has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 27° in January. About 54 inches of rain fall in a normal year.
On November 14 Gleason normally reaches 59° and falls to 38°. The record high is 80°, in 1978; the record low 16°, in 1986. The most rain on this date, 1.54 in, fell in 1957.
Normals 1991–2020 and records since 1924 at Dresden, 7 miles northwest. NOAA, through RCC-ACIS.
