−8° on Nov. 17, 2019, the coldest reading for this week of the year since 1960. Next is −4° in 2018.
Maidstone’s center stands about 860 ft above sea level. Within three miles the land runs from 850 ft to 1,790 ft, a difference of 940 ft: steep hill country. The highest named summit within 15 miles is Mount Cabot, about 4,150 ft, 13 miles southeast.
Under the town center the state geologic map shows Albee Formation (metasandstone, metasiltstone, phyllite), from the Middle Cambrian to Early Ordovician, 485 to 500 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. 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, metasiltstone, phyllite. Age: Middle Cambrian to Early Ordovician, 485 to 500 million years old. About 5 mi of the line.
Syenite. Age: Jurassic, 145 to 202 million years old. About 5 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Metaclastic. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Quartzite. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Quartz-monzodiorite. Age: Early Devonian to Late Devonian, 376 to 404 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. 3 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 Maidstone reaches Long Island Sound and the Atlantic Ocean by way of Maidstone Brook and the Connecticut: about 350 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Maidstone; river miles along the main stem, rounded.
Maidstone has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 0° in January. A normal year brings about 81 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Maidstone normally reaches 42° and falls to 22°. The record high is 64°, in 1989; the record low −6°, in 2019. The most rain on this date, 0.60 in, fell in 1975.
Normals 1991–2020 and records since 1960 at Colebrook 3 SW, 15 miles north, 260 ft higher. NOAA, through RCC-ACIS.
