3.09 inches of rain fell in two days, the most for this week of the year since records began in 1983. The next wettest, 2.79 inches, fell in 2018.
Arkwright’s center stands about 720 ft above sea level. Within three miles the land runs from 630 ft to 850 ft, a difference of 220 ft: rolling country. The highest named summit within 15 miles is Windmill Hill, about 1,200 ft, 14 miles northwest.
Under the town center the state geologic map shows Sillimanite schist and sillimanite-mica schist (mica-schist), from the Neoproterozoic to Cambrian, 487 to 1,000 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 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 12 mi of the line.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Metavolcanic. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Gneiss. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Amphibolite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Schist. Age: Neoproterozoic, 542 to 1,000 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 Arkwright reaches the Atlantic Ocean by way of Beaverdam Creek, Fairforest Creek, the Tyger, the Broad, the Congaree, the Santee and the South Santee: about 280 river miles.
Lake on the way: Lib Pines Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Arkwright; river miles along the main stem, rounded.
Arkwright has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 31° in January. About 50 inches of rain fall in a normal year.
On November 14 Arkwright normally reaches 64° and falls to 38°. The record high is 79°, in 2007; the record low 19°, in 2013. The most rain on this date, 1.33 in, fell in 2024.
