The Caratunk 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.
Caratunk’s center stands about 2,100 ft above sea level. Within three miles the land runs from 1,050 ft to 2,550 ft, a difference of 1,500 ft: steep hill country. The highest named summit within 15 miles is Moxie Mountain, about 2,920 ft, 1 miles southeast.
Under the town center the state geologic map shows Devonian gabbro - ultramafic rocks (gabbro, ultramafic), from the Devonian, 359 to 422 million years old.
The section below crosses 8 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.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 million years old. About 6 mi of the line.
Mudstone. Age: Devonian, 359 to 422 million years old. About 6 mi of the line.
Gabbro, ultramafic. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Gabbro. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Quartzite. Age: Cambrian to Ordovician, 445 to 542 million years old. About 2 mi of the line.
Schist. Age: Devonian, 359 to 422 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 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 Caratunk reaches the Atlantic Ocean by way of the Robinson Pond Outler, the Pleasant Pond Stream and the Kennebec: about 140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Caratunk; river miles along the main stem, rounded.
