3.38 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.23 inches, fell in 2018.
Chesterfield’s center stands about 290 ft above sea level. Within three miles the land runs from 150 ft to 370 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Gordon Mountain, about 630 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Richtex Formation (slate), from the Middle Cambrian to Ordovician, 445 to 521 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. 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 7 mi of the line.
Slate, argillite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.
Slate. Age: Middle Cambrian to Ordovician, 445 to 521 million years old. About 3 mi of the line.
Sand, gravel. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.
Metavolcanic. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.

A raindrop that lands in Chesterfield reaches the Atlantic Ocean by way of Indian Creek, Thompson Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 190 river miles.
150 miles of the trip are on the Great Pee Dee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chesterfield; river miles along the main stem, rounded.
Chesterfield has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 31° in January. About 49 inches of rain fall in a normal year.
On November 14 Chesterfield normally reaches 65° and falls to 40°. The record high is 83°, in 1964; the record low 20°, in 1977. The most rain on this date, 2.00 in, fell in 1940.
Normals 1991–2020 and records since 1893 at Cheraw, 12 miles east, 140 ft lower. NOAA, through RCC-ACIS.
