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.
Morven’s center stands about 370 ft above sea level. Within three miles the land runs from 210 ft to 420 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Gordon Mountain, about 630 ft, 12 miles west-northwest.
Under the town center the state geologic map shows Middendorf Formation (sand), from the Cretaceous, 66 to 145 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 41×. 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. Age: Cretaceous, 66 to 145 million years old. About 10 mi of the line.
Slate, argillite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Conglomerate, sandstone, mudstone. Age: Triassic, 202 to 252 million years old. About 4 mi of the line.
Phyllite, schist. 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 2 mi of the line.
Sand, gravel. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.

A raindrop that lands in Morven reaches the Atlantic Ocean by way of Jones Creek, the Pee Dee, the Great Pee Dee, Schooner Creek and the Waccamaw: about 190 river miles.
150 miles of the trip are on the Great Pee Dee.

Morven 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 Morven 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, 13 miles south-southeast, 220 ft lower. NOAA, through RCC-ACIS.
