4.64 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 4.11 inches, fell in 2009.
Motley’s center stands about 810 ft above sea level. Within three miles the land runs from 590 ft to 990 ft, a difference of 400 ft: hilly country. The highest named summit within 15 miles is Smith Mountain, about 2,060 ft, 13 miles west-southwest.
Under the town center the state geologic map shows Alligator Back Formation - Feldspathic metagraywacke, from the Neoproterozoic to Cambrian, 487 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 29×. 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 13 mi of the line.
Metagraywacke. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 7 mi of the line.
Amphibolite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 0.6 mi of the line.
Marble. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 0.3 mi of the line.

A raindrop that lands in Motley reaches Albemarle Sound and the Atlantic Ocean by way of Sycamore Creek and the Roanoke: about 290 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 Motley; river miles along the main stem, rounded.
Motley has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 26° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 43 inches of water.
On November 14 Motley normally reaches 59° and falls to 35°. The record high is 79°, in 1999; the record low 15°, in 1920. The most rain on this date, 1.97 in, fell in 1972.
