3.79 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 3.33 inches, fell in 2009.
Waxhaw’s center stands about 680 ft above sea level. Within three miles the land runs from 510 ft to 750 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Felsic Metavolcanic Rock (metadacite, metarhyolite, metavolcanic), from the Neoproterozoic to Cambrian, 487 to 1,000 million years old.
The section below crosses 8 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.
Phyllite, schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 10 mi of the line.
Metadacite, metarhyolite, metavolcanic. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Metagabbro, metadiorite. Age: Neoproterozoic to Paleozoic, 252 to 1,000 million years old. About 4 mi of the line.
Metagranite, metadiorite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Metagranite. Age: Neoproterozoic to Middle Cambrian, 520 to 650 million years old. About 2 mi of the line.
Amphibolite, gneiss. Age: Neoproterozoic to Paleozoic, 252 to 1,000 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. 2 smaller units along the line are not listed.

A raindrop that lands in Waxhaw reaches the Atlantic Ocean by way of Blythe Creek, Twelvemile Creek, the Catawba, the Wateree, the Congaree, the Santee and the South Santee: about 270 river miles.
Lake on the way: Lib Pines Lake.
90 miles of the trip are on the Wateree.

Waxhaw has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 30° in January. About 48 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Waxhaw normally reaches 64° and falls to 38°. The record high is 83°, in 1951; the record low 15°, in 1920. The most rain on this date, 1.68 in, fell in 1997.
