The Whitingham 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.
Whitingham’s center stands about 1,650 ft above sea level. Within three miles the land runs from 1,350 ft to 2,210 ft, a difference of 860 ft: hilly country. The highest named summit within 15 miles is Mount Snow, about 3,600 ft, 12 miles north.
Under the town center the state geologic map shows Biotite-quartz-plagioclase gneiss, from the Mesoproterozoic, 1.2 to 1.6 billion years old.
The section below crosses 16 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. 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.
Granofels. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 3 mi of the line.
Schist. Age: Mesoproterozoic, 1.2 to 1.4 billion years old. About 3 mi of the line.
Schist. Age: Early Devonian, 394 to 422 million years old. About 3 mi of the line.
Schist. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
Schist. Age: Early Devonian, 394 to 422 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. 10 smaller units along the line are not listed.

A raindrop that lands in Whitingham reaches Long Island Sound and the Atlantic Ocean by way of the Deerfield and the Connecticut: about 170 river miles.
120 miles of the trip are on the Connecticut.
