Chesterfield’s center stands about 1,220 ft above sea level. Within three miles the land runs from 90 ft to 1,460 ft, a difference of 1,370 ft: steep hill country. The highest named summit within 15 miles is Jay Mountains, about 3,600 ft, 15 miles southwest.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss, metaanorthosite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.
Anorthosite, metasedimentary. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Shale. Age: Late Ordovician, 445 to 459 million years old. About 2 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Sandstone. Age: Cambrian, 487 to 497 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. 2 smaller units along the line are not listed.

A raindrop that lands in Chesterfield reaches the St. Lawrence River by way of Little Trout Brook and the Richelieu: about 130 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.

Chesterfield has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 13° in January. A normal year brings about 88 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Chesterfield normally reaches 47° and falls to 33°. The record high is 67°, in 1959; the record low 10°, in 1996. The most rain on this date, 1.14 in, fell in 2009.
Normals 1991–2020 and records since 1883 from the Burlington Area threaded record (Burlington International Airport, 15 miles east, 890 ft lower). NOAA, through RCC-ACIS.
