74° on Nov. 16, 1993, the hottest reading for this week of the year since 1888. Next is 73° in 2020.
Mansfield’s center stands about 660 ft above sea level. Within three miles the land runs from 230 ft to 720 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Stickney Hill, about 1,320 ft, 14 miles north.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 25×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist, gneiss. Age: Cambrian to Ordovician, 445 to 542 million years old. About 4 mi of the line.
Granofels, schist. Age: Cambrian to Ordovician, 445 to 542 million years old. About 3 mi of the line.
Schist, calc-silicate-rock. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Gabbro. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Gneiss. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 9 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 Mansfield reaches Long Island Sound and the Atlantic Ocean by way of Schoolhouse Brook, the Fenton, the Natchaug, the Shetucket and the Thames: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mansfield; river miles along the main stem, rounded.
Mansfield has a hot-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 19° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Mansfield normally reaches 51° and falls to 34°. The record high is 67°, in 1902; the record low 10°, in 1905. The most rain on this date, 2.21 in, fell in 1937.
