3.65 inches of rain fell in two days, the most for this week of the year since records began in 1947. The next wettest, 2.77 inches, fell in 2008.
Hartsville’s center stands about 220 ft above sea level. Within three miles the land runs from 160 ft to 330 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Horseshoe Mountain, about 420 ft, 15 miles north.
Under the town center the state geologic map shows Duplin Formation (sand, clay), from the Pliocene, 2.6 to 5.3 million years old.

Sand, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 15 mi of the line.
Clay, sand. Age: Late Cretaceous, 66 to 72 million years old. About 9 mi of the line.

A raindrop that lands in Hartsville reaches the Atlantic Ocean by way of Black Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 160 river miles.
95 miles of the trip are on the Great Pee Dee.
