0° on Nov. 16, 1933, the coldest reading for this week of the year since 1893. Next is 6° in 1905.
Putney’s center stands about 630 ft above sea level. Within three miles the land runs from 220 ft to 1,240 ft, a difference of 1,020 ft: steep hill country. The highest named summit within 15 miles is Whites Hill, about 2,690 ft, 14 miles west.
Under the town center the state geologic map shows Waits River Formation - slate and phyllite member (slate, phyllite, mica-schist), from the Silurian to Early Devonian, 394 to 425 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 6 mi of the line.
Muscovite-schist, metagraywacke. Age: Silurian to Early Devonian, 394 to 425 million years old. About 5 mi of the line.
Phyllite, mica-schist. Age: Silurian to Early Devonian, 394 to 425 million years old. About 3 mi of the line.
Slate, phyllite. Age: Late Ordovician, 445 to 459 million years old. About 3 mi of the line.
Metagraywacke. Age: Early Devonian, 410 to 414 million years old. About 2 mi of the line.
Granite. Age: Late Devonian, 360 to 368 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Putney reaches Long Island Sound and the Atlantic Ocean by way of the Connecticut: about 160 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Putney; river miles along the main stem, rounded.
Putney has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 10° in January. A normal year brings about 60 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Putney normally reaches 47° and falls to 27°. The record high is 68°, in 1989; the record low 6°, in 1905. The most rain on this date, 1.61 in, fell in 1937.
Normals 1991–2020 and records since 1893 at Keene, 11 miles east-southeast, 120 ft lower. NOAA, through RCC-ACIS.
