Trumbull Center’s center stands about 100 ft above sea level. Within three miles the land runs from 40 ft to 500 ft, a difference of 460 ft: hilly country. The highest named summit within 15 miles is Bogus Mountain, about 850 ft, 15 miles west-northwest.
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 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Orthogneiss. Age: Middle Ordovician, 459 to 471 million years old. About 5 mi of the line.
Gneiss, amphibolite. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Schist. Age: Silurian to Devonian, 359 to 445 million years old. About 3 mi of the line.
Schist, granofels. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Gneiss. Age: Early Devonian to Middle Devonian, 393 to 419 million years old. About 1 mi of the line.
Gneiss. Age: Early Ordovician to Middle Ordovician, 459 to 487 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 Trumbull Center reaches Long Island Sound and the Atlantic Ocean by way of Booth Hill Brook and the Pequonnock: about 4 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Trumbull Center; river miles along the main stem, rounded.
Trumbull Center has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 25° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Trumbull Center normally reaches 54° and falls to 39°. The record high is 68°, in 1959; the record low 20°, in 1986. The most rain on this date, 2.84 in, fell in 1972.
