71° on Nov. 16, 1927, the hottest reading for this week of the year since 1893. Next is 70° in 1909.
Wilton’s center stands about 570 ft above sea level. Within three miles the land runs from 380 ft to 1,040 ft, a difference of 660 ft: hilly country. The highest named summit within 15 miles is Mount Blue, about 3,180 ft, 11 miles north-northwest.
Under the town center the state geologic map shows Silurian Sangerville Formation, Anasagunticook member (metasandstone), from the Silurian, 434 to 445 million years old.
The section below crosses 10 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.
Metasandstone, pelitic-schist, metasiltstone. Age: Early Devonian, 394 to 422 million years old. About 7 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Schist. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Shale, sandstone. Age: Silurian, 428 to 434 million years old. About 3 mi of the line.
Metasandstone. Age: Silurian, 434 to 445 million years old. About 2 mi of the line.
Marble. Age: Silurian, 428 to 445 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. 4 smaller units along the line are not listed.

A raindrop that lands in Wilton reaches the Atlantic Ocean by way of the Varnum Stream, the Wilson Stream, the Sandy and the Kennebec: about 140 river miles.
95 miles of the trip are on the Kennebec.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wilton; river miles along the main stem, rounded.
Wilton has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 6° in January. A normal year brings about 94 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Wilton normally reaches 45° and falls to 26°. The record high is 66°, in 1930; the record low 3°, in 2019. The most rain on this date, 2.35 in, fell in 1937.
Normals 1991–2020 and records since 1893 at Farmington, 8 miles north-northeast, 160 ft lower. NOAA, through RCC-ACIS.
