3.33 inches of rain fell in two days, the most for this week of the year since records began in 1901. The next wettest, 2.85 inches, fell in 1979.
Wedgefield’s center stands about 260 ft above sea level. Within three miles the land runs from 110 ft to 370 ft, a difference of 260 ft: rolling country.
Under the town center the state geologic map shows Neogene strata (undifferentiated) (sand, gravel), from the Tertiary Neogene to Quaternary, less than 23 million years old.
The section below crosses 5 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 11 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Clay, sand. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Sand, gravel. Age: Tertiary Neogene to Quaternary, less than 23 million years old. About 2 mi of the line.
Sand, limestone. Age: Tertiary, 2.6 to 66 million years old. About 1 mi of the line.

A raindrop that lands in Wedgefield reaches the Atlantic Ocean by way of Cane Savannah Creek, the Pocotaligo and the Black River: about 150 river miles.
110 miles of the trip are on the Black River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wedgefield; river miles along the main stem, rounded.
Wedgefield has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 33° in January. About 49 inches of rain fall in a normal year.
On November 14 Wedgefield normally reaches 65° and falls to 40°. The record high is 83°, in 1989; the record low 22°, in 2013. The most rain on this date, 1.65 in, fell in 1940.
Normals 1991–2020 and records since 1901 at Sumter, 10 miles east-northeast. NOAA, through RCC-ACIS.
