81° on Nov. 15, 1973, the hottest reading for this week of the year since 1891. Next is 80° in 1931.
Shepherdstown’s center stands about 410 ft above sea level. Within three miles the land runs from 290 ft to 560 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Black Rock, about 1,870 ft, 15 miles northeast.
Under the town center the state geologic map shows Conococheague Formation (limestone), from the Cambrian, 487 to 542 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Limestone. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
Limestone, shale. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Limestone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Metabasalt. Age: Proterozoic to Mesoproterozoic, 1 to 2.5 billion years old. 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. 6 smaller units along the line are not listed.

A raindrop that lands in Shepherdstown reaches Chesapeake Bay and the Atlantic Ocean by way of the Potomac: about 190 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shepherdstown; river miles along the main stem, rounded.
Shepherdstown has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. About 39 inches of rain fall in a normal year.
On November 14 Shepherdstown normally reaches 56° and falls to 35°. The record high is 77°, in 1989; the record low 13°, in 1986. The most rain on this date, 1.41 in, fell in 1972.
