71° on Nov. 11, 2020, the hottest reading for this week of the year since 1993. Next is 70° in 2022.
Greene’s center stands about 360 ft above sea level. Within three miles the land runs from 240 ft to 670 ft, a difference of 430 ft: hilly country. The highest named summit within 15 miles is Streaked Mountain, about 1,740 ft, 14 miles west-northwest.
Under the town center the state geologic map shows Silurian Sangerville Formation, Patch Mountain member (marble), from the Silurian, 428 to 445 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 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Marble. Age: Silurian, 428 to 445 million years old. About 9 mi of the line.
Shale, sandstone. Age: Silurian, 428 to 434 million years old. About 8 mi of the line.
Sandstone. Age: Late Ordovician to Silurian, 428 to 459 million years old. About 2 mi of the line.
Granite. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Schist, slate. Age: Silurian, 428 to 445 million years old. About 1 mi of the line.
Shale. Age: Silurian, 428 to 445 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Greene reaches the Atlantic Ocean by way of Stetson Brook, the Androscoggin and the Kennebec: about 60 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greene; river miles along the main stem, rounded.
Greene 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 78 inches of snow; with the rain, that comes to about 50 inches of water.
On November 14 Greene normally reaches 46° and falls to 27°. The record high is 64°, in 2010; the record low 6°, in 2019. The most rain on this date, 1.02 in, fell in 2018.
Normals 1991–2020 and records since 1993 at Durham, 13 miles south, 220 ft lower. NOAA, through RCC-ACIS.
