26° on Nov. 14, 2019, the coldest reading for this week of the year since 1945. Next is 27° in 1967.
Carrollton’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 80 ft, a difference of 80 ft: gently rolling country. Open water lies within three miles.
Under the town center the state geologic map shows Tabb Formation; Sedgefield Member (sand), from the Quaternary, less than 2.6 million years old.
The section below crosses 7 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: Quaternary, less than 2.6 million years old. About 6 mi of the line.
Sand. Age: Tertiary, 2.6 to 66 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sand, silt. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Tertiary to Quaternary, less than 66 million years old. About 2 mi of the line.
Unconsolidated. Age: Holocene, less than 12,000 years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.
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 Carrollton reaches Chesapeake Bay and the Atlantic Ocean by way of the James: about 12 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Carrollton; river miles along the main stem, rounded.
Carrollton has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 34° in January. About 46 inches of rain fall in a normal year, with about 3 inches of snow.
On November 14 Carrollton normally reaches 62° and falls to 45°. The record high is 81°, in 1993; the record low 26°, in 2019. The most rain on this date, 1.27 in, fell in 1945.
Normals 1991–2020 and records since 1945 at Norfolk Nas, 13 miles east. NOAA, through RCC-ACIS.
