Graniteville’s center stands about 1,290 ft above sea level. Within three miles the land runs from 680 ft to 1,930 ft, a difference of 1,250 ft: steep hill country. The highest named summit within 15 miles is Signal Mountain, about 3,360 ft, 9 miles east-northeast.
The section below crosses 10 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.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 11 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Granodiorite. Age: Late Devonian, 364 to 372 million years old. About 2 mi of the line.
Quartzite, phyllite, mica-schist. Age: Early Devonian, 404 to 414 million years old. About 2 mi of the line.
Granofels, quartzite. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 1 mi of the line.
Slate, phyllite, mica-schist. Age: Silurian to Early Devonian, 394 to 425 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. 4 smaller units along the line are not listed.

A raindrop that lands in Graniteville reaches the St. Lawrence River by way of Stevens Branch, the Winooski and the Richelieu: about 190 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
80 miles of the trip are on the Richelieu.

Graniteville has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 7° in January. About 39 inches of rain fall in a normal year.
On November 14 Graniteville normally reaches 44° and falls to 27°. The record high is 65°, in 2011; the record low 5°, in 2018. The most rain on this date, 1.74 in, fell in 2009.
