The Rich Square plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
6.31 inches of rain fell in two days, the most for this week of the year since records began in 1948. The next wettest, 5.15 inches, fell in 2009.
Rich Square’s center stands about 80 ft above sea level. Within three miles the land runs from 60 ft to 140 ft, a difference of 80 ft: gently rolling country.
Under the town center the state geologic map shows Cape Fear Formation (sandstone, mudstone), from the Cretaceous, 66 to 145 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 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.
Clay. Age: Tertiary, 2.6 to 66 million years old. About 16 mi of the line.
Sandstone, mudstone. Age: Cretaceous, 66 to 145 million years old. About 8 mi of the line.

A raindrop that lands in Rich Square reaches Albemarle Sound and the Atlantic Ocean by way of Urahaw Swamp, Potecasi Creek and the Chowan: about 80 river miles.

Rich Square has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 29° in January. A normal year brings about 5 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Rich Square normally reaches 62° and falls to 38°. The record high is 81°, in 1989; the record low 18°, in 1976. The most rain on this date, 1.14 in, fell in 2008.
