Reevesville’s center stands about 120 ft above sea level. Within three miles the land runs from 90 ft to 170 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Duplin Formation (sand, clay), from the Pliocene, 2.6 to 5.3 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, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 16 mi of the line.
Sand, limestone. Age: Tertiary, 2.6 to 66 million years old. About 8 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 Reevesville reaches the Atlantic Ocean by way of Bear Branch, Polk Swamp, the Edisto and the North Edisto: about 85 river miles.
55 miles of the trip are on the Edisto.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Reevesville; river miles along the main stem, rounded.
