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.
Blenheim’s center stands about 130 ft above sea level. Within three miles the land runs from 80 ft to 170 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Bear Bluff Formation (sand, limestone), from the Tertiary, 2.6 to 66 million years old.
The section below crosses 4 rock units mapped at the surface.

Sand, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 8 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 7 mi of the line.
Sand, limestone. Age: Tertiary, 2.6 to 66 million years old. About 7 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Blenheim reaches the Atlantic Ocean by way of the Three Creeks, the Great Pee Dee, Schooner Creek and the Waccamaw: about 140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Blenheim; river miles along the main stem, rounded.
Blenheim 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 Blenheim 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.
