Tunbridge’s center stands about 610 ft above sea level. Within three miles the land runs from 520 ft to 1,680 ft, a difference of 1,160 ft: steep hill country. The highest named summit within 15 miles is Rochester Mountain, about 2,930 ft, 13 miles west.
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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. 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 17 mi of the line.
Quartzite, phyllite, mica-schist. Age: Early Devonian, 404 to 414 million years old. About 3 mi of the line.
Phyllite, mica-schist. Age: Silurian to Early Devonian, 394 to 425 million years old. About 2 mi of the line.
Quartz-feldspar-schist, granofels. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 2 mi of the line.
Quartz-feldspar-schist. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 0.8 mi of the line.
Granofels, quartzite. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 0.3 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 Tunbridge reaches Long Island Sound and the Atlantic Ocean by way of the First Branch White, the White River and the Connecticut: about 240 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tunbridge; river miles along the main stem, rounded.
Tunbridge has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. About 40 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1950 at Union Village Dam, 14 miles east-southeast, 150 ft lower. NOAA, through RCC-ACIS.
