71° on Nov. 11, 2002, the hottest reading for this week of the year since 1884. Next is 69° in 1909.
Wilder’s center stands about 440 ft above sea level. Within three miles the land runs from 330 ft to 1,220 ft, a difference of 890 ft: hilly country. The highest named summit within 15 miles is Croydon Peak, about 2,740 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Ammonoosuc Volcanics of Billings (1935) - undivided (metavolcanic, metasedimentary), from the Middle Ordovician to Late Ordovician, 445 to 471 million years old.
The section below crosses 17 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mica-schist, quartzite. Age: Early Devonian, 394 to 422 million years old. About 6 mi of the line.
Granite, aplite. Age: Late Ordovician, 445 to 459 million years old. About 3 mi of the line.
Granite. Age: Late Ordovician, 445 to 459 million years old. About 3 mi of the line.
Orthogneiss. Age: Late Ordovician, 445 to 459 million years old. About 2 mi of the line.
Quartzite. Age: Early Devonian, 394 to 422 million years old. About 1 mi of the line.
Slate, phyllite. Age: Late Ordovician, 445 to 459 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 11 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Wilder reaches Long Island Sound and the Atlantic Ocean by way of Dothan Brook and the Connecticut: about 220 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wilder; river miles along the main stem, rounded.
Wilder has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 13° in January. A normal year brings about 61 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Wilder normally reaches 48° and falls to 31°. The record high is 66°, in 1973; the record low 6°, in 1905. The most rain on this date, 1.19 in, fell in 2007.
Normals 1991–2020 and records since 1884 at Hanover, 3 miles north-northeast, 140 ft higher. NOAA, through RCC-ACIS.
