Maine’s center stands about 1,350 ft above sea level. Within three miles the land runs from 1,310 ft to 1,440 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Granite to granodiorite (granite, granodiorite), from the Neoarchean, 2.5 to 2.8 billion years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 59×. 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, granodiorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 16 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 8 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 Maine reaches Hudson Bay by way of the Otter Tail, the Red River of the North and the Nelson: about 1,270 river miles. Past the border it runs north through Canada to Hudson Bay.
Lake on the way: Lake Winnipeg.
550 miles of the trip are on the Red River of the North.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Maine; river miles along the main stem, rounded.
Maine has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about −2° in January. About 28 inches of rain fall in a normal year.
On November 14 Maine normally reaches 37° and falls to 22°. The record high is 63°, in 1981; the record low 6°, in 1965. The most rain on this date, 0.47 in, fell in 2024.
Normals 1991–2020 and records since 1940 at Ottertail, 13 miles east. NOAA, through RCC-ACIS.
