5.40 inches of rain fell in two days, the most for this week of the year since records began in 1930. The next wettest, 3.88 inches, fell in 2006.
Horse Pasture’s center stands about 1,090 ft above sea level. Within three miles the land runs from 830 ft to 1,280 ft, a difference of 450 ft: hilly country. The highest named summit within 15 miles is No Business Mountain, about 2,020 ft, 12 miles west.
Under the town center the state geologic map shows Fork Mountain Formation (mica-schist), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 9 mi of the line.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 5 mi of the line.
Metagraywacke, muscovite-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Norite. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Granite. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Biotite-gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Horse Pasture reaches Albemarle Sound and the Atlantic Ocean by way of Tanyard Branch, Jordan Creek, the Smith, the Dan and the Roanoke: about 330 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 Horse Pasture; river miles along the main stem, rounded.
Horse Pasture has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 24° in January. A normal year brings about 9 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Horse Pasture normally reaches 61° and falls to 32°. The record high is 79°, in 1999; the record low 16°, in 1976. The most rain on this date, 1.79 in, fell in 1972.
Normals 1991–2020 and records since 1930 at Martinsville Filter Plant, 7 miles northeast, 310 ft lower. NOAA, through RCC-ACIS.
