North Haverhill’s center stands about 490 ft above sea level. Within three miles the land runs from 390 ft to 1,140 ft, a difference of 750 ft: hilly country. The highest named summit within 15 miles is Mount Moosilauke, about 4,790 ft, 11 miles east-southeast.
The section below crosses 13 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.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 4 mi of the line.
Metasandstone, metasiltstone, phyllite. Age: Middle Cambrian to Early Ordovician, 485 to 500 million years old. About 4 mi of the line.
Metasedimentary. Age: Early Devonian, 394 to 422 million years old. About 4 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 3 mi of the line.
Granite. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Quartzite. Age: Early Devonian, 394 to 422 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 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 North Haverhill reaches Long Island Sound and the Atlantic Ocean by way of Clark Brook and the Connecticut: about 260 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Haverhill; river miles along the main stem, rounded.
