3.62 inches of rain fell in two days, the most for this week of the year since records began in 1947. The next wettest, 3.20 inches, fell in 1979.
Keysville’s center stands about 660 ft above sea level. Within three miles the land runs from 490 ft to 670 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Virgilina Greenstone, from the Neoproterozoic, 542 to 1,000 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metavolcanic, schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 7 mi of the line.
Greenstone. Age: Neoproterozoic, 542 to 1,000 million years old. About 6 mi of the line.
Phyllite, slate. Age: Neoproterozoic, 542 to 1,000 million years old. About 5 mi of the line.
Biotite-gneiss, schist. Age: Proterozoic, 542 to 2,500 million years old. About 4 mi of the line.
Biotite-gneiss. Age: Proterozoic, 542 to 2,500 million years old. About 2 mi of the line.

A raindrop that lands in Keysville reaches Albemarle Sound and the Atlantic Ocean by way of Bentleys Branch, Twittys Creek, Roanoke Creek and the Roanoke: about 240 river miles.
Lake on the way: Roanoke Rapids Lake.
130 miles of the trip are on the Roanoke.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Keysville; river miles along the main stem, rounded.
Keysville 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 46 inches of water.
On November 14 Keysville normally reaches 62° and falls to 38°. The record high is 78°, in 1989; the record low 18°, in 1986. The most rain on this date, 0.70 in, fell in 1972.
Normals 1991–2020 and records since 1947 at Chase City, 18 miles south, 250 ft lower. NOAA, through RCC-ACIS.
