Kershaw’s center stands about 530 ft above sea level. Within three miles the land runs from 360 ft to 610 ft, a difference of 250 ft: rolling country.
Under the town center the state geologic map shows Peedee Formation - Black Creek Group, undivided (clay, sand), from the Late Cretaceous, 66 to 72 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 42×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sand. Age: Late Cretaceous, 66 to 72 million years old. About 10 mi of the line.
Metavolcanic. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 10 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Metagranite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.

A raindrop that lands in Kershaw reaches the Atlantic Ocean by way of Lick Creek, Hanging Rock Creek, the Little Lynches, the Lynches, Clark Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 200 river miles.
110 miles of the trip are on the Lynches.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kershaw; river miles along the main stem, rounded.
Kershaw has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 31° in January. About 38 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1893 at Wateree Dam, 16 miles south-southwest, 300 ft lower. NOAA, through RCC-ACIS.
