Roxbury’s center stands about 1,030 ft above sea level. Within three miles the land runs from 900 ft to 2,540 ft, a difference of 1,640 ft: steep hill country. The highest named summit within 15 miles is Mount Ellen, about 4,060 ft, 11 miles west-northwest.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. 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 4 mi of the line.
Phyllite, muscovite-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Quartzite, phyllite, mica-schist. Age: Early Devonian, 404 to 414 million years old. About 3 mi of the line.
Mica-schist, phyllite. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 3 mi of the line.
Granofels, quartzite. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 2 mi of the line.
Muscovite-schist, gneiss, quartzite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 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. 8 smaller units along the line are not listed.

Roxbury straddles the St. Lawrence Divide. Rain on the east side runs to the St. Lawrence River; most of the rest goes to Long Island Sound and the Atlantic Ocean.
From the center of town, a raindrop reaches Long Island Sound and the Atlantic Ocean by way of the Third Branch White, the White River and the Connecticut: about 270 river miles. One that lands on the east side reaches the St. Lawrence River by way of Bull Run, the Dog, the Winooski and the Richelieu: about 190 river miles. The St. Lawrence carries it on to the Atlantic.
220 miles of the trip are on the Connecticut.

Roxbury 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 Roxbury 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.
