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.
Jonesville’s center stands about 680 ft above sea level. Within three miles the land runs from 510 ft to 730 ft, a difference of 220 ft: rolling country.
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 49×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Carboniferous to Permian, 252 to 359 million years old. About 13 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Metavolcanic. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Biotite-gneiss. 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 0.9 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 Jonesville reaches the Atlantic Ocean by way of Swink Creek, Fairforest Creek, the Tyger, the Broad, the Congaree, the Santee and the South Santee: about 270 river miles.
Lake on the way: Lib Pines Lake.
70 miles of the trip are on the Santee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Jonesville; river miles along the main stem, rounded.
Jonesville 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 Jonesville 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.
