10° on Nov. 16, 1996, the coldest reading for this week of the year since 1937. Next is 14° in 1956.
Candlewood Isle’s center stands about 520 ft above sea level. Within three miles the land runs from 230 ft to 1,090 ft, a difference of 860 ft: hilly country. The highest named summit within 15 miles is Dennis Hill, about 1,370 ft, 15 miles northwest.
Under the town center the state geologic map shows Dalton Formation (gneiss, quartzite), from the Early Cambrian, 521 to 542 million years old.
The section below crosses 13 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 18×. 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, granofels. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 7 mi of the line.
Pelitic-schist, gneiss, amphibolite. Age: Early Cambrian to Middle Ordovician, 459 to 542 million years old. About 3 mi of the line.
Marble. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 3 mi of the line.
Gneiss, amphibolite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Gneiss. Age: Early Devonian to Middle Devonian, 393 to 419 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. 7 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 Candlewood Isle reaches Long Island Sound and the Atlantic Ocean by way of the Housatonic: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Candlewood Isle; river miles along the main stem, rounded.
Candlewood Isle has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 21° in January. A normal year brings about 49 inches of snow; with the rain, that comes to about 53 inches of water.
On November 14 Candlewood Isle normally reaches 51° and falls to 34°. The record high is 73°, in 1993; the record low 16°, in 1939. The most rain on this date, 2.42 in, fell in 1937.
Normals 1991–2020 and records since 1937 at Danbury, 6 miles south-southeast, 120 ft lower. NOAA, through RCC-ACIS.
