5.00 inches of rain fell in two days, the most for this week of the year since records began in 1878. The next wettest, 3.01 inches, fell in 1940.
Marvin’s center stands about 690 ft above sea level. Within three miles the land runs from 560 ft to 720 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Gabbro of Concord Plutonic Suite, from the Early Ordovician to Early Devonian, 399 to 479 million years old.
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 63×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

Gabbro. Age: Early Ordovician to Early Devonian, 399 to 479 million years old. About 5 mi of the line.
Metavolcanic. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 5 mi of the line.
Granitic. Age: Ordovician to Devonian, 359 to 487 million years old. About 1 mi of the line.
Granite. Age: Early Devonian to Middle Devonian, 385 to 415 million years old. About 1 mi of the line.
Metagranite. Age: Neoproterozoic to Cambrian, 487 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Marvin reaches the Atlantic Ocean by way of Marvin Branch, Sixmile 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.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marvin; river miles along the main stem, rounded.
Marvin has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 32° in January. About 44 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Marvin normally reaches 63° and falls to 40°. The record high is 80°, in 1879; the record low 21°, in 2013. The most rain on this date, 1.23 in, fell in 1972.
