3.60 inches of rain fell in two days, the most for this week of the year since records began in 1946. The next wettest, 3.51 inches, fell in 2009.
Clio’s center stands about 200 ft above sea level. Within three miles the land runs from 140 ft to 230 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Duplin Formation (sand, clay), from the Pliocene, 2.6 to 5.3 million years old.
The section below crosses 2 rock units mapped at the surface.

Sand, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 17 mi of the line.
Sand, limestone. Age: Tertiary, 2.6 to 66 million years old. About 7 mi of the line.

A raindrop that lands in Clio reaches the Atlantic Ocean by way of the Hagins Prong, the Three Creeks, the Great Pee Dee, Schooner Creek and the Waccamaw: about 150 river miles.
120 miles of the trip are on the Great Pee Dee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clio; river miles along the main stem, rounded.
Clio has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 33° in January. About 47 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Clio normally reaches 66° and falls to 42°. The record high is 82°, in 1989; the record low 24°, in 2013. The most rain on this date, 1.61 in, fell in 1947.
