4.30 inches of rain fell in two days, the most for this week of the year since records began in 1891. The next wettest, 4.15 inches, fell in 2018.
Pittsboro’s center stands about 400 ft above sea level. Within three miles the land runs from 360 ft to 620 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Terrells Mountain, about 790 ft, 10 miles north.
Under the town center the state geologic map shows Felsic Metavolcanic Rock (metadacite, metarhyolite, metavolcanic), from the Neoproterozoic to Cambrian, 487 to 1,000 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 34×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metadacite, metarhyolite, metavolcanic. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 12 mi of the line.
Conglomerate, sandstone, mudstone. Age: Triassic, 202 to 252 million years old. About 5 mi of the line.
Metabasalt. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 5 mi of the line.
Metaandesite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 1 mi of the line.
Metaconglomerate. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 0.6 mi of the line.

A raindrop that lands in Pittsboro reaches the Atlantic Ocean by way of Roberson Creek, the Haw and the Cape Fear: about 210 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pittsboro; river miles along the main stem, rounded.
