Greenville’s center stands about 120 ft above sea level. Within three miles the land runs from 90 ft to 160 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Miccosukee Formation (sand, clay, gravel), 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.
Sandstone, limestone. Age: Middle Miocene, 12 to 16 million years old. About 19 mi of the line.
Sand, clay, gravel. Age: Late Pliocene, 2.6 to 3.6 million years old. About 5 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 Greenville reaches the Gulf of America by way of Sundown Creek, Alligator Creek and the Aucilla: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greenville; river miles along the main stem, rounded.
