The DeFuniak Springs plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
DeFuniak Springs’s center stands about 230 ft above sea level. Within three miles the land runs from 120 ft to 280 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Citronelle Formation (sand), from the Late Pliocene, 2.6 to 3.6 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.
Sand. Age: Late Pliocene, 2.6 to 3.6 million years old. About 14 mi of the line.
Sand, clay. Age: Middle Miocene to Early Pliocene, 3.6 to 16 million years old. About 10 mi of the line.

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 DeFuniak Springs reaches Choctawhatchee Bay and the Gulf of America by way of Bruce Creek and the Choctawhatchee: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of DeFuniak Springs; river miles along the main stem, rounded.
