Sutton’s center stands about 1,180 ft above sea level. Within three miles the land runs from 890 ft to 1,780 ft, a difference of 890 ft: hilly country. The highest named summit within 15 miles is East Mountain, about 3,440 ft, 13 miles east.
Under the town center the state geologic map shows Waits River Formation - carbonaceous phyllite and limestone member (phyllite, limestone), from the Silurian to Early Devonian, 394 to 425 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. 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, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 15 mi of the line.
Quartzite. Age: Early Devonian, 394 to 422 million years old. About 4 mi of the line.
Quartzite, phyllite, mica-schist. Age: Early Devonian, 404 to 414 million years old. About 3 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Sutton reaches Long Island Sound and the Atlantic Ocean by way of Calendar Brook, the Passumpsic and the Connecticut: about 310 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sutton; river miles along the main stem, rounded.
Sutton has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about −1° in January. About 43 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1993 at East Haven, 7 miles east, 180 ft lower. NOAA, through RCC-ACIS.
