Glen Lyn’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,480 ft to 3,240 ft, a difference of 1,760 ft: steep hill country. The highest named summit within 15 miles is Butt Mountain, about 4,220 ft, 13 miles east.
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 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Ordovician to Silurian, 422 to 487 million years old. About 3 mi of the line.
Sandstone, shale. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Shale, sandstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Shale, sandstone, mudstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Black-shale. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Sandstone, limestone, shale. Age: Silurian to Devonian, 359 to 445 million 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. 7 smaller units along the line are not listed.

A raindrop that lands in Glen Lyn reaches the Gulf of America by way of the New River, the Kanawha, the Ohio and the Mississippi: about 1,870 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Glen Lyn; river miles along the main stem, rounded.
Glen Lyn has a humid subtropical climate. Summer afternoons average 83° in July; winter nights fall to about 23° in January. A normal year brings about 23 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Glen Lyn normally reaches 56° and falls to 31°. The record high is 78°, in 1993; the record low 8°, in 1986. The most rain on this date, 0.63 in, fell in 2008.
