The Tar Heel 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.
5.48 inches of rain fell in two days, the most for this week of the year since records began in 1903. The next wettest, 3.75 inches, fell in 2008.
Tar Heel’s center stands about 140 ft above sea level. Within three miles the land runs from 50 ft to 180 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Black Creek Formation (clay, sand), from the Cretaceous, 66 to 145 million years old.
The section below crosses 2 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.
Clay, sand. Age: Cretaceous, 66 to 145 million years old. About 24 mi of the line.
Clay. Age: Tertiary, 2.6 to 66 million years old. About 0.6 mi of the line.

A raindrop that lands in Tar Heel reaches the Atlantic Ocean by way of the Cape Fear: about 110 river miles.

Tar Heel has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 35° in January. About 43 inches of rain fall in a normal year.
On November 14 Tar Heel normally reaches 66° and falls to 42°. The record high is 83°, in 1931; the record low 21°, in 2013. The most rain on this date, 1.61 in, fell in 2008.
