The Davidson 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.
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.
Davidson’s center stands about 730 ft above sea level. Within three miles the land runs from 670 ft to 860 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Metamorphosed Quartz Diorite (metadiorite), from the Neoproterozoic to Paleozoic, 252 to 1,000 million years old.
The section below crosses 5 rock units mapped at the surface.

Metadiorite. Age: Neoproterozoic to Paleozoic, 252 to 1,000 million years old. About 13 mi of the line.
Biotite-gneiss. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 8 mi of the line.
Syenite. Age: Early Devonian, 404 to 405 million years old. About 2 mi of the line.
Gabbro. Age: Early Ordovician to Early Devonian, 399 to 479 million years old. About 0.7 mi of the line.
Mica-schist. Age: Neoproterozoic, 542 to 1,000 million years old. About 0.3 mi of the line.

A raindrop that lands in Davidson reaches the Atlantic Ocean by way of the South Prong West Branch Rocky, the Rocky, the Pee Dee, the Great Pee Dee, Schooner Creek and the Waccamaw: about 300 river miles.
150 miles of the trip are on the Great Pee Dee.

Davidson 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 Davidson 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.
