Wallingford’s center stands about 610 ft above sea level. Within three miles the land runs from 550 ft to 2,180 ft, a difference of 1,630 ft: steep hill country. The highest named summit within 15 miles is Killington Peak, about 4,190 ft, 12 miles northeast.
Under the town center the state geologic map shows Winooski Dolostone (dolostone, phyllite), from the Middle Cambrian, 497 to 521 million years old.
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 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, phyllite. Age: Middle Cambrian, 497 to 521 million years old. About 4 mi of the line.
Gneiss. Age: Mesoproterozoic, 1.2 to 1.6 billion years old. About 3 mi of the line.
Phyllite. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Muscovite-schist. Age: Mesoproterozoic, 1.2 to 1.4 billion years old. About 3 mi of the line.
Slate, phyllite. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Dolostone. Age: Early Cambrian, 521 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. 8 smaller units along the line are not listed.

A raindrop that lands in Wallingford reaches the St. Lawrence River by way of Otter Creek and the Richelieu: about 230 river miles. The St. Lawrence carries it on to the Atlantic.
Lake on the way: Lake Champlain.
110 miles of the trip are on Otter Creek.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wallingford; river miles along the main stem, rounded.
Wallingford has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 8° in January. A normal year brings about 75 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Wallingford normally reaches 47° and falls to 26°. The record high is 69°, in 1989; the record low 1°, in 2019. The most rain on this date, 1.20 in, fell in 1937.
Normals 1991–2020 and records since 1916 at Rutland, 11 miles north. NOAA, through RCC-ACIS.
