73° on Nov. 11, 2020, the hottest reading for this week of the year since 1973. Next is 67° in 2022.
Parkman’s center stands about 590 ft above sea level. Within three miles the land runs from 400 ft to 870 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Russell Mountain, about 2,180 ft, 11 miles northwest.
Under the town center the state geologic map shows Silurian Sangerville Formation (shale, sandstone), from the Silurian, 428 to 434 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, sandstone. Age: Silurian, 428 to 434 million years old. About 10 mi of the line.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 million years old. About 7 mi of the line.
Schist. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Marble. Age: Silurian, 428 to 445 million years old. About 0.8 mi of the line.
Sandstone, shale. Age: Silurian, 422 to 445 million years old. About 0.5 mi of the line.
Conglomerate. Age: Silurian, 428 to 445 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Parkman reaches the Atlantic Ocean by way of Snow Brook, the Main Stream Sebasticook, the Sebasticook and the Kennebec: about 130 river miles.
60 miles of the trip are on the Kennebec.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Parkman; river miles along the main stem, rounded.
Parkman has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 4° in January. A normal year brings about 77 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Parkman normally reaches 45° and falls to 26°. The record high is 63°, in 2010; the record low 4°, in 1986. The most rain on this date, 1.14 in, fell in 2018.
Normals 1991–2020 and records since 1973 at Dover-Foxcroft Wwtp, 13 miles east-northeast, 220 ft lower. NOAA, through RCC-ACIS.
