Whitefield’s center stands about 970 ft above sea level. Within three miles the land runs from 870 ft to 1,830 ft, a difference of 960 ft: steep hill country. The highest named summit within 15 miles is Mount Lafayette, about 5,200 ft, 15 miles south.
Under the town center the state geologic map shows Metavolcanic and metasedimentary rocks of the lower part of Ammonoosuc Volcanics, undivided (metavolcanic, metasedimentary), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite. Age: Late Ordovician, 445 to 459 million years old. About 4 mi of the line.
Metavolcanic, metasedimentary. Age: Middle Ordovician, 459 to 471 million years old. About 3 mi of the line.
Quartz-syenite. Age: Late Ordovician, 445 to 459 million years old. About 2 mi of the line.
Granite. Age: Late Devonian, 359 to 384 million years old. About 2 mi of the line.
Tonalite. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 2 mi of the line.
Granite. Age: Middle Jurassic to Late Jurassic, 145 to 175 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. 9 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 Whitefield reaches Long Island Sound and the Atlantic Ocean by way of the Johns and the Connecticut: about 310 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Whitefield; river miles along the main stem, rounded.
Whitefield has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 5° in January. About 37 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1996 at Whitefield Mount Washington Regional Airport, 3 miles east. NOAA, through RCC-ACIS.
