Denmark’s center stands about 530 ft above sea level. Within three miles the land runs from 370 ft to 960 ft, a difference of 590 ft: hilly country. The highest named summit within 15 miles is Green Hills, about 2,360 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Carboniferous alkali feldspar granite (muscovite accessory mineral), from the Carboniferous, 299 to 359 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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 15 mi of the line.
Mudstone, limestone. Age: Silurian to Devonian, 359 to 445 million years old. About 5 mi of the line.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 3 mi of the line.
Foid-syenite. Age: Mesozoic, 66 to 252 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 Denmark reaches the Atlantic Ocean by way of Beaver Brook and the Saco: about 80 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Denmark; river miles along the main stem, rounded.
Denmark 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 Denmark 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, 7 miles west. NOAA, through RCC-ACIS.
