82° on Nov. 11, 2022, the hottest reading for this week of the year since 1891. Next is 81° in 2001.
Dunn’s center stands about 210 ft above sea level. Within three miles the land runs from 150 ft to 250 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Middendorf Formation (sand), from the Cretaceous, 66 to 145 million years old.
The section below crosses 3 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. Age: Cretaceous, 66 to 145 million years old. About 14 mi of the line.
Clay, sand. Age: Cretaceous, 66 to 145 million years old. About 8 mi of the line.
Sandstone, mudstone. Age: Cretaceous, 66 to 145 million years old. About 2 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 Dunn reaches the Atlantic Ocean by way of Juniper Creek, the Black River, the South River, the Black River and the Cape Fear: about 160 river miles.
80 miles of the trip are on the South River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dunn; river miles along the main stem, rounded.
Dunn has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 29° in January. About 47 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1891 at Lillington, 13 miles west-northwest. NOAA, through RCC-ACIS.
