Wesson’s center stands about 450 ft above sea level. Within three miles the land runs from 350 ft to 520 ft, a difference of 170 ft: gently rolling country.
Under the town center the state geologic map shows Citronelle formation (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 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.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 10 mi of the line.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 10 mi of the line.
Sand. Age: Miocene, 5.3 to 23 million years old. About 4 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 Wesson reaches the Gulf of America by way of Fords Creek, Little Bahala Creek, Bahala Creek and the Pearl: about 240 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wesson; river miles along the main stem, rounded.
