Ariton’s center stands about 460 ft above sea level. Within three miles the land runs from 280 ft to 530 ft, a difference of 250 ft: rolling country.
The section below crosses 6 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.
Clay, sand. Age: Paleocene, 56 to 66 million years old. About 7 mi of the line.
Silt, clay. Age: Paleocene, 56 to 66 million years old. About 6 mi of the line.
Claystone. Age: Eocene, 34 to 56 million years old. About 5 mi of the line.
Limestone. Age: Paleocene, 56 to 66 million years old. About 2 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sand. Age: Eocene, 34 to 56 million years old. About 2 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 Ariton reaches Choctawhatchee Bay and the Gulf of America by way of Bear Creek, Claybank Creek and the Choctawhatchee: about 150 river miles.
110 miles of the trip are on the Choctawhatchee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ariton; river miles along the main stem, rounded.
