The Woodstock 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.
Woodstock’s center stands about 1,500 ft above sea level. Within three miles the land runs from 670 ft to 2,220 ft, a difference of 1,550 ft: steep hill country. The highest named summit within 15 miles is Plumbago Mountain, about 2,650 ft, 14 miles northwest.
Under the town center the state geologic map shows Devonian Carrabassett Formation (schist), from the Devonian, 359 to 422 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metasandstone. Age: Silurian, 434 to 445 million years old. About 8 mi of the line.
Schist. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Tonalite. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Shale, sandstone. Age: Silurian, 425 to 434 million years old. About 3 mi of the line.
Shale, sandstone. Age: Silurian, 425 to 434 million years old. About 1 mi of the line.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 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. 4 smaller units along the line are not listed.

A raindrop that lands in Woodstock reaches the Atlantic Ocean by way of Andrews Brook, the Little Androscoggin, the Androscoggin and the Kennebec: about 95 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Woodstock; river miles along the main stem, rounded.
