3.11 inches of rain fell in two days, the most for this week of the year since records began in 1895. The next wettest, 2.64 inches, fell in 2020.
Pine Crest’s center stands about 1,710 ft above sea level. Within three miles the land runs from 1,520 ft to 3,040 ft, a difference of 1,520 ft: steep hill country. The highest named summit within 15 miles is Unaka Mountain, about 5,200 ft, 11 miles south.
Under the town center the state geologic map shows Knox Group, including Jonesboro Limestone, Newala Formation, Mascot Dolomite, Kingsport Formation, Longview Dolomite, Chepultepec Dolomite, Copper Ridge Dolomite, Conococheague Limestone (limestone, dolostone), from the Cambrian to Ordovician, 445 to 542 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 7×. 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 to Ordovician, 445 to 542 million years old. About 12 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Sandstone, arkose, conglomerate. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Shale, sandstone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Quartzite. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 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. 3 smaller units along the line are not listed.

A raindrop that lands in Pine Crest reaches the Gulf of America by way of Buffalo Creek, the Watauga, the South Fork Holston, the Holston, the Tennessee, the Ohio and the Mississippi: about 1,840 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.

Pine Crest 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 48 inches of water.
On November 14 Pine Crest normally reaches 59° and falls to 33°. The record high is 84°, in 1895; the record low 13°, in 2014. The most rain on this date, 0.86 in, fell in 1915.
Normals 1991–2020 and records since 1895 at Elizabethton, 5 miles northeast, 220 ft lower. NOAA, through RCC-ACIS.
