23° on Nov. 15, 1969, the coldest reading for this week of the year since 1954. Next is 25° in 2013.
Arcadia Lakes’s center stands about 250 ft above sea level. Within three miles the land runs from 180 ft to 390 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Sand Mountain, about 410 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Cape Fear/Eutaw Formations (sand, gravel), from the Cretaceous, 66 to 145 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 6 mi of the line.
Sand, gravel. Age: Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Clay, sand. Age: Late Cretaceous, 66 to 72 million years old. About 5 mi of the line.
Metavolcanic. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Mylonite. Age: Carboniferous to Permian, 252 to 359 million years old. About 3 mi of the line.
Metasiltstone, metasandstone. Age: Middle Cambrian, 497 to 521 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Arcadia Lakes reaches the Atlantic Ocean by way of Gills Creek, the Congaree, the Santee and the South Santee: about 190 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 Arcadia Lakes; river miles along the main stem, rounded.
Arcadia Lakes has a humid subtropical climate. Summer afternoons average 96° in July; winter nights fall to about 37° in January. About 48 inches of rain fall in a normal year.
On November 14 Arcadia Lakes normally reaches 69° and falls to 44°. The record high is 84°, in 2007; the record low 25°, in 2013. The most rain on this date, 1.70 in, fell in 2008.
Normals 1991–2020 and records since 1954 at Columbia University Of Sc, 5 miles southwest. NOAA, through RCC-ACIS.
