Valparaiso’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 140 ft, a difference of 140 ft: gently rolling country. Open water lies within three miles.
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 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. Age: Late Pliocene, 2.6 to 3.6 million years old. About 12 mi of the line.
Sand, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.

Rain that falls on Valparaiso runs only a short way, about 4 miles, to Choctawhatchee Bay and the Gulf of America.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Valparaiso; river miles along the main stem, rounded.
