16° on Nov. 11, 2017, the coldest reading for this week of the year since 1992. Next is 19° in 1996.
Parkesburg’s center stands about 540 ft above sea level. Within three miles the land runs from 450 ft to 860 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Welsh Mountain, about 1,080 ft, 11 miles north.
Under the town center the state geologic map shows Conestoga Formation (limestone), from the Cambrian to Ordovician, 445 to 542 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mica-schist. Age: Paleozoic, 252 to 542 million years old. About 7 mi of the line.
Mica-schist, quartzite. Age: Paleozoic, 252 to 542 million years old. About 4 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Quartzite, schist. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Gneiss. Age: Precambrian. About 2 mi of the line.
Gneiss. Age: Precambrian. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units along the line are not listed.

A raindrop that lands in Parkesburg reaches Delaware Bay and the Atlantic Ocean by way of Buck Run, West Branch Brandywine Creek, Brandywine Creek, the Christina and the Delaware: about 85 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Parkesburg; river miles along the main stem, rounded.
Parkesburg has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 24° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Parkesburg normally reaches 54° and falls to 37°. The record high is 70°, in 1993; the record low 25°, in 2004. The most rain on this date, 0.50 in, fell in 2008.
Normals 1991–2020 and records since 1992 at New Holland 2 SE, 11 miles northwest. NOAA, through RCC-ACIS.
