3.30 inches of rain fell in two days, the most for this week of the year since records began in 1889. The next wettest, 3.01 inches, fell in 1935.
Sneedville’s center stands about 1,170 ft above sea level. Within three miles the land runs from 1,130 ft to 2,370 ft, a difference of 1,240 ft: steep hill country. The highest named summit within 15 miles is Notch Rock, about 2,950 ft, 15 miles north.
The section below crosses 18 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Cambrian, 487 to 542 million years old. About 5 mi of the line.
Black-shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 3 mi of the line.
Shale. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Limestone, dolostone, shale. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone. Age: Ordovician, 445 to 487 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. 12 smaller units along the line are not listed.

A raindrop that lands in Sneedville reaches the Gulf of America by way of the Clinch, the Tennessee, the Ohio and the Mississippi: about 1,740 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical), Pickwick Lake and Cummings Lake.
970 miles of the trip are on the Mississippi.

Sneedville has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 25° in January. A normal year brings about 6 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Sneedville normally reaches 59° and falls to 35°. The record high is 79°, in 1993; the record low 10°, in 1906. The most rain on this date, 0.76 in, fell in 1915.
Normals 1991–2020 and records since 1889 at Rogersville 1 NE, 15 miles east-southeast, 180 ft higher. NOAA, through RCC-ACIS.
