Albany’s center stands about 3,180 ft above sea level. Within three miles the land runs from 750 ft to 3,090 ft, a difference of 2,340 ft: mountain country. The highest named summit within 15 miles is Mount Carrigain, about 4,650 ft, 13 miles northwest.
Under the town center the state geologic map shows Mount Osceola Granite, Granite containing hornblende and, locally, hastingsite, ferrohedenbergite, or fayalite, from the Early Jurassic to Middle Jurassic, 164 to 202 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 5×. 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: Middle Jurassic to Late Jurassic, 145 to 175 million years old. About 11 mi of the line.
Granite. Age: Carboniferous, 299 to 359 million years old. About 5 mi of the line.
Granite. Age: Early Jurassic to Middle Jurassic, 164 to 202 million years old. About 4 mi of the line.
Monzonite. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Granodiorite. Age: Early Devonian, 394 to 422 million years old. About 0.9 mi of the line.
Syenite. Age: Jurassic, 145 to 202 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 Albany reaches the Atlantic Ocean by way of the Chocorua, the Bearcamp, the Ossipee and the Saco: about 90 river miles.
Lake on the way: Ossipee Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Albany; river miles along the main stem, rounded.
