73° on Nov. 11, 2020, the hottest reading for this week of the year since 1947. Next is 70° in 2002.
Stetson’s center stands about 240 ft above sea level. Within three miles the land runs from 210 ft to 520 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Peaked Mountain, about 1,200 ft, 13 miles south-southeast.
Under the town center the state geologic map shows Silurian - Ordovician Vassalboro Formation (sandstone), from the Late Ordovician to Silurian, 428 to 459 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 13 mi of the line.
Schist, slate. Age: Silurian, 428 to 445 million years old. About 8 mi of the line.
Quartzite, calc-silicate-rock. Age: Silurian to Devonian, 359 to 445 million years old. About 2 mi of the line.
Marble, calc-silicate-rock, metasedimentary. Age: Silurian, 428 to 445 million years old. About 0.6 mi of the line.
Sandstone, shale. Age: Silurian, 422 to 445 million years old. About 0.4 mi of the line.

A raindrop that lands in Stetson reaches the Atlantic Ocean by way of the Stetson Stream, the East Branch Sebasticook, the Sebasticook and the Kennebec: about 110 river miles.
Lake on the way: Sebasticook Lake.
60 miles of the trip are on the Kennebec.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stetson; river miles along the main stem, rounded.
Stetson has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 6° in January. A normal year brings about 72 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Stetson normally reaches 47° and falls to 28°. The record high is 67°, in 2022; the record low 5°, in 2019. The most rain on this date, 1.03 in, fell in 1949.
Normals 1991–2020 and records since 1947 at Corinna, 5 miles west-northwest. NOAA, through RCC-ACIS.
