Gibson’s center stands about 410 ft above sea level. Within three miles the land runs from 350 ft to 470 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Webb Mountain, about 620 ft, 13 miles east-northeast.
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 2 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 24 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.6 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 Gibson reaches the Gulf of America by way of Hog Creek, the North Fork Forked Deer, the Forked Deer, the Obion and the Mississippi: about 900 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gibson; river miles along the main stem, rounded.
Gibson has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 28° in January. About 56 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Gibson normally reaches 62° and falls to 37°. The record high is 81°, in 1931; the record low 12°, in 2019. The most rain on this date, 1.90 in, fell in 1915.
Normals 1991–2020 and records since 1883 at Milan Experiment Station, 8 miles east-northeast. NOAA, through RCC-ACIS.
