Northfield’s center stands about 310 ft above sea level. Within three miles the land runs from 180 ft to 1,310 ft, a difference of 1,130 ft: steep hill country. The highest named summit within 15 miles is Jolly Mountain, about 2,040 ft, 15 miles west-northwest.
Under the town center the state geologic map shows Turner Falls Sandstone (conglomerate, sandstone), from the Early Jurassic, 175 to 202 million years old.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist, phyllite. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Arkose, siltstone, sandstone. Age: Late Triassic, 202 to 237 million years old. About 3 mi of the line.
Gneiss. Age: Late Ordovician, 449 to 453 million years old. About 3 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 3 mi of the line.
Gneiss. Age: Late Ordovician to Silurian, 440 to 454 million years old. About 2 mi of the line.
Granite, granodiorite, tonalite. Age: Late Ordovician, 445 to 459 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. 9 smaller units along the line are not listed.

A raindrop that lands in Northfield reaches Long Island Sound and the Atlantic Ocean by way of Roaring Brook and the Connecticut: about 130 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Northfield; river miles along the main stem, rounded.
Northfield has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 14° in January. About 42 inches of rain fall in a normal year.
On November 14 Northfield normally reaches 50° and falls to 30°. The record high is 62°, in 2011; the record low 12°, in 1996. The most rain on this date, 0.79 in, fell in 2009.
Normals 1991–2020 and records since 1996 at Orange Municipal Airport, 12 miles southeast, 230 ft higher. NOAA, through RCC-ACIS.
