Bar Harbor’s center stands about 60 ft above sea level. Within three miles the land runs from 0 ft to 1,410 ft, a difference of 1,410 ft: steep hill country. Open water lies within three miles. The highest named summit within 15 miles is Cadillac Mountain, about 1,520 ft, 3 miles south-southwest.
Under the town center the state geologic map shows Devonian - Silurian Bar Harbor Formation (sandstone, siltstone), from the Silurian to Devonian, 359 to 445 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Devonian, 359 to 422 million years old. About 6 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 0.9 mi of the line.
Sandstone, siltstone. Age: Silurian to Devonian, 359 to 445 million years old. About 0.8 mi of the line.
Mafic-volcanic, felsic-volcanic. Age: Ordovician to Devonian, 359 to 487 million years old. About 0.8 mi of the line.
Quartz-monzonite. Age: Devonian, 359 to 422 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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.
Rain that falls on Bar Harbor runs only a short way, about 2 miles, to the Atlantic Ocean.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bar Harbor; river miles along the main stem, rounded.
