Baldwin’s center stands about 730 ft above sea level. Within three miles the land runs from 290 ft to 1,210 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Pleasant Mountain, about 1,990 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Devonian - Silurian Rindgemere Formation lower member (mudstone, limestone), from the Silurian to Devonian, 359 to 445 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 17×. 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: Carboniferous, 299 to 359 million years old. About 9 mi of the line.
Mudstone, limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 6 mi of the line.
Granodiorite. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 1 mi of the line.
Quartz-alkali-feldspar-syenite. Age: Cretaceous, 66 to 145 million years old. About 1 mi of the line.
Schist, slate. Age: Silurian, 428 to 445 million years old. About 1 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.

A raindrop that lands in Baldwin reaches the Atlantic Ocean by way of Dug Hill Brook and the Saco: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Baldwin; river miles along the main stem, rounded.
Baldwin has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 7° in January. About 47 inches of rain fall in a normal year.
On November 14 Baldwin normally reaches 47° and falls to 26°. The record high is 63°, in 2016; the record low 4°, in 2019. The most rain on this date, 2.06 in, fell in 2009.
Normals 1991–2020 and records since 1996 at Fryeburg Eastern Slopes Regl Airport, 15 miles northwest, 280 ft lower. NOAA, through RCC-ACIS.
