74° on Nov. 11, 2020, the hottest reading for this week of the year since 1993. Next is 67° in 2002.
Chesterville’s center stands about 380 ft above sea level. Within three miles the land runs from 340 ft to 860 ft, a difference of 520 ft: hilly country. The highest named summit within 15 miles is Saddleback Mountain, about 2,540 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Devonian granite (muscovite accessory mineral), from the Devonian, 359 to 422 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 20×. 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: Devonian, 359 to 422 million years old. About 10 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 5 mi of the line.
Metasandstone. Age: Silurian, 434 to 445 million years old. About 3 mi of the line.
Shale, sandstone. Age: Silurian, 428 to 434 million years old. About 2 mi of the line.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Schist. Age: Early Devonian, 394 to 422 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. 3 smaller units along the line are not listed.

A raindrop that lands in Chesterville reaches the Atlantic Ocean by way of the Little Norridgewock Stream, the Wilson Stream, the Sandy and the Kennebec: about 130 river miles.
95 miles of the trip are on the Kennebec.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chesterville; river miles along the main stem, rounded.
Chesterville has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 7° in January. A normal year brings about 86 inches of snow; with the rain, that comes to about 49 inches of water.
Normals 1991–2020 and records since 1993 at New Sharon, 7 miles northeast, 100 ft higher. NOAA, through RCC-ACIS.
