15° on Nov. 14, 1986, the coldest reading for this week of the year since 1893. Next is 17° in 1933.
Crimora’s center stands about 1,260 ft above sea level. Within three miles the land runs from 1,190 ft to 2,130 ft, a difference of 940 ft: steep hill country. The highest named summit within 15 miles is Humpback Mountain, about 3,620 ft, 14 miles south.
Under the town center the state geologic map shows Elbrook Formation (dolostone, limestone), from the Cambrian, 487 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 8×. 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 5 mi of the line.
Quartzite, conglomerate, sandstone. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Metabasalt. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Dolostone, limestone. Age: Ordovician, 445 to 487 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. 7 smaller units along the line are not listed.

A raindrop that lands in Crimora reaches Chesapeake Bay and the Atlantic Ocean by way of the South River, the South Fork Shenandoah, the Shenandoah and the Potomac: about 340 river miles.
180 miles of the trip are on the Potomac.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Crimora; river miles along the main stem, rounded.
Crimora has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 28° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Crimora normally reaches 58° and falls to 40°. The record high is 81°, in 1955; the record low 15°, in 1986. The most rain on this date, 2.36 in, fell in 1972.
