Singers Glen’s center stands about 1,690 ft above sea level. Within three miles the land runs from 1,240 ft to 2,540 ft, a difference of 1,300 ft: steep hill country. The highest named summit within 15 miles is Flagpole Knob, about 4,370 ft, 15 miles west.
The section below crosses 11 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.
Sandstone. Age: Devonian, 359 to 422 million years old. About 8 mi of the line.
Dolostone, limestone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 3 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 2 mi of the line.
Shale, sandstone. Age: Ordovician, 445 to 487 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Singers Glen reaches Chesapeake Bay and the Atlantic Ocean by way of Joes Creek, Linville Creek, the North Fork Shenandoah, the Shenandoah and the Potomac: about 330 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 Singers Glen; river miles along the main stem, rounded.
Singers Glen has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 23° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Singers Glen normally reaches 56° and falls to 33°. The record high is 78°, in 1924; the record low 9°, in 1920. The most rain on this date, 1.00 in, fell in 1908.
