85° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 84° in 1993.
Ebony’s center stands about 320 ft above sea level. Within three miles the land runs from 200 ft to 390 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Biotite Gneiss (biotite-gneiss), from the Proterozoic, 542 to 2,500 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 64×. 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: Proterozoic, 542 to 2,500 million years old. About 13 mi of the line.
Gneiss, biotite-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Granitic. Age: Early Pennsylvanian to Permian, 270 to 320 million years old. About 2 mi of the line.
Granite. Age: Proterozoic, 542 to 2,500 million years old. About 2 mi of the line.
Gravel, sand. Age: Tertiary, 2.6 to 66 million years old. About 0.7 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 Ebony reaches Albemarle Sound and the Atlantic Ocean by way of Pigeonroost Creek and the Roanoke: about 160 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 Ebony; river miles along the main stem, rounded.
Ebony has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 29° in January. About 44 inches of rain fall in a normal year.
On November 14 Ebony normally reaches 63° and falls to 39°. The record high is 78°, in 1964; the record low 20°, in 2019. The most rain on this date, 0.64 in, fell in 1997.
Normals 1991–2020 and records since 1948 at John H Kerr Dam, 18 miles west. NOAA, through RCC-ACIS.
