70° on Nov. 15, 1956, the hottest reading for this week of the year since 1893. Next is 69° in 1909.
Wilton’s center stands about 350 ft above sea level. Within three miles the land runs from 280 ft to 1,100 ft, a difference of 820 ft: hilly country. The highest named summit within 15 miles is Spruce Mountain, about 2,010 ft, 9 miles west-northwest.
Under the town center the state geologic map shows Beekmantown Group (dolostone, limestone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 7 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.

Metasedimentary, migmatite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 9 mi of the line.
Charnockite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Dolostone, limestone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Melange. Age: Middle Ordovician, 459 to 471 million years old. About 0.9 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Wilton reaches New York Harbor and the Atlantic Ocean by way of Snook Kill and the Hudson: about 210 river miles.
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 82° in July; winter nights fall to about 10° in January. About 38 inches of rain fall in a normal year.
On November 14 Wilton normally reaches 47° and falls to 28°. The record high is 67°, in 1973; the record low 5°, in 1905. The most rain on this date, 1.45 in, fell in 2009.
Normals 1991–2020 and records since 1893 from the Glens Falls Area threaded record (Glens Falls/Floyd Bennett Memorial Airport, 13 miles north-northeast). NOAA, through RCC-ACIS.
