75° on Nov. 11, 2020, the hottest reading for this week of the year since 1996. Next is 70° in 2022.
Wilmot’s center stands about 900 ft above sea level. Within three miles the land runs from 660 ft to 1,600 ft, a difference of 940 ft: steep hill country. The highest named summit within 15 miles is Mount Cardigan, about 3,110 ft, 14 miles north.
Under the town center the state geologic map shows Kinsman Granodiorite, from the Early Devonian, 394 to 422 million years old.
The section below crosses 6 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.
Granodiorite. Age: Early Devonian, 394 to 422 million years old. About 8 mi of the line.
Quartz-diorite, tonalite, granodiorite. Age: Early Devonian, 394 to 422 million years old. About 6 mi of the line.
Granite. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Metaclastic. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Metasedimentary. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Granodiorite. Age: Early Devonian, 394 to 422 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.
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 Wilmot reaches the Atlantic Ocean by way of Cassey Brook, Cascade Brook, the Blackwater, the Contoocook and the Merrimack: about 140 river miles.
100 miles of the trip are on the Merrimack.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wilmot; river miles along the main stem, rounded.
Wilmot has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 13° in January. About 49 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1996 at Salisbury, 11 miles southeast, 350 ft lower. NOAA, through RCC-ACIS.
