The Whitney plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
3.09 inches of rain fell in two days, the most for this week of the year since records began in 1983. The next wettest, 2.79 inches, fell in 2018.
Whitney’s center stands about 770 ft above sea level. Within three miles the land runs from 700 ft to 910 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Thicketty Mountain, about 1,260 ft, 12 miles northeast.
Under the town center the state geologic map shows Biotite gneiss and muscovite-biotite gneiss (biotite-gneiss), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. 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: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 16 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Gneiss. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Amphibolite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 0.9 mi of the line.
Schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 0.4 mi of the line.

A raindrop that lands in Whitney reaches the Atlantic Ocean by way of Lawsons Fork Creek, the Pacolet, the Broad, the Congaree, the Santee and the South Santee: about 300 river miles.
Lake on the way: Lib Pines Lake.
75 miles of the trip are on the Broad.

Whitney has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 31° in January. About 50 inches of rain fall in a normal year.
On November 14 Whitney normally reaches 64° and falls to 38°. The record high is 79°, in 2007; the record low 19°, in 2013. The most rain on this date, 1.33 in, fell in 2024.
