The Woodford plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Woodford’s center stands about 2,190 ft above sea level. Within three miles the land runs from 1,320 ft to 2,740 ft, a difference of 1,420 ft: steep hill country. The highest named summit within 15 miles is Glastenbury Mountain, about 3,770 ft, 7 miles north.
Under the town center the state geologic map shows Dalton Formation - dark phyllite member, from the Neoproterozoic to Early Cambrian, 521 to 1,000 million years old.
The section below crosses 18 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 7 mi of the line.
Phyllite. Age: Neoproterozoic, 542 to 1,000 million years old. About 3 mi of the line.
Graywacke, siltstone. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Mica-schist, phyllite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 2 mi of the line.
Paragneiss. Age: Mesoproterozoic, 1.2 to 1.2 billion years old. About 1 mi of the line.
Phyllite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 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. 12 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 Woodford reaches New York Harbor and the Atlantic Ocean by way of Bolles Brook, Roaring Branch Walloomsac Brook, the Walloomsac, the Hoosic and the Hudson: about 210 river miles.
170 miles of the trip are on the Hudson.
