3.65 inches of rain fell in two days, the most for this week of the year since records began in 1947. The next wettest, 2.77 inches, fell in 2008.
Pine Ridge’s center stands about 260 ft above sea level. Within three miles the land runs from 200 ft to 390 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is King Sand Hills, about 590 ft, 15 miles north-northwest.
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 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 57×. 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 13 mi of the line.
Sand, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 11 mi of the line.

A raindrop that lands in Pine Ridge reaches the Atlantic Ocean by way of Beaverdam Creek, Black Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 170 river miles.
95 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 Pine Ridge; river miles along the main stem, rounded.
Pine Ridge has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 32° in January. About 48 inches of rain fall in a normal year.
On November 14 Pine Ridge normally reaches 66° and falls to 40°. The record high is 82°, in 1951; the record low 22°, in 2013. The most rain on this date, 0.72 in, fell in 1997.
Normals 1991–2020 and records since 1947 at Hartsville, 7 miles east. NOAA, through RCC-ACIS.
