Cabot’s center stands about 1,080 ft above sea level. Within three miles the land runs from 900 ft to 2,130 ft, a difference of 1,230 ft: steep hill country. The highest named summit within 15 miles is Signal Mountain, about 3,360 ft, 14 miles south.
Under the town center the state geologic map shows Gile Mountain Formation - rhythmically graded member (quartzite, phyllite, mica-schist), from the Early Devonian, 404 to 414 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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 13 mi of the line.
Quartzite, phyllite, mica-schist. Age: Early Devonian, 404 to 414 million years old. About 11 mi of the line.

A raindrop that lands in Cabot reaches the St. Lawrence River by way of the Winooski and the Richelieu: about 200 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
85 miles of the trip are on the Winooski.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cabot; river miles along the main stem, rounded.
Cabot has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 9° in January. A normal year brings about 87 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Cabot normally reaches 46° and falls to 29°. The record high is 64°, in 1989; the record low 3°, in 1905. The most rain on this date, 1.64 in, fell in 1937.
Normals 1991–2020 and records since 1894 at Saint Johnsbury, 15 miles east, 380 ft lower. NOAA, through RCC-ACIS.
