76° on Nov. 11, 2020, the hottest reading for this week of the year since 1963. Next is 74° in 1993.
Kingston’s center stands about 140 ft above sea level. Within three miles the land runs from 90 ft to 300 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Mount Pawtuckaway, about 990 ft, 15 miles north-northwest.
Under the town center the state geologic map shows Merrimack Group, Eliot Formation (phyllite, quartzite, mica-schist), from the Ordovician to Silurian, 422 to 487 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 38×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite, quartzite, mica-schist. Age: Ordovician to Silurian, 422 to 487 million years old. About 11 mi of the line.
Granofels, biotite-schist. Age: Ordovician to Silurian, 422 to 487 million years old. About 5 mi of the line.
Granite. Age: Silurian, 422 to 428 million years old. About 3 mi of the line.
Schist, granofels. Age: Ordovician to Silurian, 422 to 487 million years old. About 2 mi of the line.
Tonalite, granodiorite. Age: Silurian, 422 to 428 million years old. About 1 mi of the line.
Granite. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 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 Kingston reaches the Atlantic Ocean by way of the Powwow and the Merrimack: about 25 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kingston; river miles along the main stem, rounded.
Kingston has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 14° in January. A normal year brings about 57 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Kingston normally reaches 50° and falls to 30°. The record high is 72°, in 1989; the record low 7°, in 1986. The most rain on this date, 1.25 in, fell in 2006.
Normals 1991–2020 and records since 1963 at Epping, 7 miles north-northwest. NOAA, through RCC-ACIS.
