The Quinby plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
3.28 inches of rain fell in two days, the most for this week of the year since records began in 1948. The next wettest, 2.14 inches, fell in 2008.
Quinby’s center stands about 140 ft above sea level. Within three miles the land runs from 80 ft to 180 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Alluvial Valley Swamp (sand, gravel), from the Quaternary, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, limestone. Age: Tertiary, 2.6 to 66 million years old. About 14 mi of the line.
Sand, gravel. Age: Quaternary, less than 2.6 million years old. About 7 mi of the line.
Sand, clay. Age: Pliocene, 2.6 to 5.3 million years old. About 1 mi of the line.
Sand, clay. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Limestone, sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Quinby reaches the Atlantic Ocean by way of Ashby Branch, Black Creek, the Great Pee Dee, Schooner Creek and the Waccamaw: about 120 river miles.
95 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 Quinby; river miles along the main stem, rounded.
Quinby has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 36° in January. About 45 inches of rain fall in a normal year.
On November 14 Quinby normally reaches 67° and falls to 44°. The record high is 84°, in 1993; the record low 22°, in 2013. The most rain on this date, 1.14 in, fell in 2008.
