Whitefield’s center stands about 120 ft above sea level. Within three miles the land runs from 50 ft to 390 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Patrick Mountain, about 910 ft, 14 miles northeast.
Under the town center the state geologic map shows Ordovician - Precambrian Z Cape Elizabeth Formation (slate), from the Neoproterozoic to Ordovician, 445 to 1,000 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 36×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Slate. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 18 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Felsic-volcanic, mafic-volcanic. Age: Neoproterozoic to Ordovician, 445 to 1,000 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.

A raindrop that lands in Whitefield reaches the Atlantic Ocean by way of the Sheepscot: about 30 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 78° in July; winter nights fall to about 15° in January. A normal year brings about 79 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Whitefield normally reaches 46° and falls to 33°. The record high is 62°, in 1973; the record low 11°, in 2019. The most rain on this date, 1.03 in, fell in 2006.
Normals 1991–2020 and records since 1965 at Newcastle, 10 miles south-southeast. NOAA, through RCC-ACIS.
