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.
Wallace’s center stands about 150 ft above sea level. Within three miles the land runs from 80 ft to 350 ft, a difference of 270 ft: rolling country.
Under the town center the state geologic map shows Cape Fear/Eutaw Formations (sand, gravel), from the Cretaceous, 66 to 145 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 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, gravel. Age: Quaternary, less than 2.6 million years old. About 7 mi of the line.
Sand, gravel. Age: Cretaceous, 66 to 145 million years old. About 7 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.
Biotite-gneiss, mica-schist, calc-silicate-rock. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Granite. Age: Late Mississippian to Permian, 265 to 325 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Wallace reaches the Atlantic Ocean by way of Husbands Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 170 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wallace; river miles along the main stem, rounded.
Wallace 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 Wallace 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, 3 miles west-southwest. NOAA, through RCC-ACIS.
