Wadesboro’s center stands about 540 ft above sea level. Within three miles the land runs from 290 ft to 530 ft, a difference of 240 ft: rolling country.
Under the town center the state geologic map shows Newark Supergroup, Chatham Group; Chatham Group, Undivided (conglomerate, sandstone, mudstone), from the Triassic, 202 to 252 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 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.
Conglomerate, sandstone, mudstone. Age: Triassic, 202 to 252 million years old. About 12 mi of the line.
Granite. Age: Late Mississippian to Permian, 265 to 325 million years old. About 6 mi of the line.
Gravel, sand. Age: Tertiary, 2.6 to 66 million years old. About 3 mi of the line.
Slate, argillite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Wadesboro reaches the Atlantic Ocean by way of Lampley Branch, North Fork Jones Creek, Jones Creek, the Pee Dee, the Great Pee Dee, Schooner Creek and the Waccamaw: about 200 river miles.
150 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 Wadesboro; river miles along the main stem, rounded.
