North Canaan’s center stands about 890 ft above sea level. Within three miles the land runs from 650 ft to 1,790 ft, a difference of 1,140 ft: steep hill country. The highest named summit within 15 miles is Mount Everett, about 2,600 ft, 9 miles northwest.
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 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Marble. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 5 mi of the line.
Phyllite, schist. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 4 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Marble. Age: Early Cambrian, 521 to 542 million years old. About 2 mi of the line.
Schist. Age: Cambrian, 487 to 542 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 North Canaan reaches Long Island Sound and the Atlantic Ocean by way of the Blackberry and the Housatonic: about 85 river miles.

North Canaan has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 14° in January. A normal year brings about 75 inches of snow; with the rain, that comes to about 53 inches of water.
On November 14 North Canaan normally reaches 46° and falls to 31°. The record high is 64°, in 1964; the record low 10°, in 2019. The most rain on this date, 0.92 in, fell in 1988.
Normals 1991–2020 and records since 1884 at Norfolk 2 SW, 5 miles southeast, 450 ft higher. NOAA, through RCC-ACIS.
