−7° on Nov. 13, 2019, the coldest reading for this week of the year since 1949. Next is 5° in 1972.
La Fargeville’s center stands about 380 ft above sea level. Within three miles the land runs from 320 ft to 470 ft, a difference of 150 ft: gently rolling country.
Under the town center the state geologic map shows Theresa Formation (dolostone), from the Cambrian to Early Ordovician, 471 to 542 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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 9 mi of the line.
Dolostone. Age: Cambrian to Early Ordovician, 471 to 542 million years old. About 8 mi of the line.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 1 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.8 mi of the line.
Quartzite, mica-schist. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 0.6 mi of the line.

A raindrop that lands in La Fargeville reaches Lake Ontario by way of the Chaumont: about 16 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of La Fargeville; river miles along the main stem, rounded.
La Fargeville has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 10° in January. About 37 inches of rain fall in a normal year.
On November 14 La Fargeville normally reaches 47° and falls to 30°. The record high is 68°, in 1994; the record low 13°, in 1996. The most rain on this date, 0.90 in, fell in 1985.
Normals 1991–2020 and records since 1949 at Watertown International Airport, 15 miles south-southwest. NOAA, through RCC-ACIS.
