Stratton Mountain’s center stands about 2,060 ft above sea level. Within three miles the land runs from 1,350 ft to 3,780 ft, a difference of 2,430 ft: mountain country. The highest named summit within 15 miles is Stratton Mountain, about 3,940 ft, 2 miles south-southwest.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Mesoproterozoic, 1.2 to 1.6 billion years old. About 6 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1.2 to 1.2 billion years old. About 5 mi of the line.
Paragneiss, metadacite. Age: Mesoproterozoic, 1.3 to 1.3 billion years old. About 3 mi of the line.
Paragneiss, quartz-feldspar-schist. Age: Mesoproterozoic, 1.2 to 1.4 billion years old. About 2 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1.3 to 1.4 billion years old. About 2 mi of the line.
Schist. Age: Mesoproterozoic, 1.2 to 1.4 billion 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. 5 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 Stratton Mountain reaches Long Island Sound and the Atlantic Ocean by way of North Branch Ball Mountain Brook, Ball Mountain Brook, the West River and the Connecticut: about 190 river miles.
150 miles of the trip are on the Connecticut.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stratton Mountain; river miles along the main stem, rounded.
Stratton Mountain has a warm-summer humid continental climate. Summer afternoons average 75° in July; winter nights fall to about 8° in January. About 51 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1940 at Peru, 10 miles north, 360 ft lower. NOAA, through RCC-ACIS.
