Dixie Union’s center stands about 160 ft above sea level. Within three miles the land runs from 100 ft to 210 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Pleistocene-Pliocene sands and gravels (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 15 mi of the line.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 6 mi of the line.
Fine-detrital. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.

A raindrop that lands in Dixie Union reaches the Atlantic Ocean by way of Dryden Creek and the Satilla: about 160 river miles.
