7° on Nov. 16, 1933, the coldest reading for this week of the year since 1892. Next is 9° in 1908.
Farmington’s center stands about 1,000 ft above sea level. Within three miles the land runs from 960 ft to 1,510 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is Kincaid Knob, about 1,780 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Monongahela Group (sandstone, siltstone, shale), from the Carboniferous, 299 to 324 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 26×. 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, siltstone, shale. Age: Carboniferous to Permian, 252 to 324 million years old. About 15 mi of the line.
Shale, siltstone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.

A raindrop that lands in Farmington reaches the Gulf of America by way of Buffalo Creek, the Monongahela, the Ohio and the Mississippi: about 2,080 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Farmington; river miles along the main stem, rounded.
Farmington has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 24° in January. About 48 inches of rain fall in a normal year.
On November 14 Farmington normally reaches 54° and falls to 36°. The record high is 77°, in 1971; the record low 11°, in 1986. The most rain on this date, 0.62 in, fell in 1993.
