72° on Nov. 11, 1999, the hottest reading for this week of the year since 1911. Next is 71° in 1973.
Fairfield’s center stands about 4,880 ft above sea level. Within three miles the land runs from 4,830 ft to 5,400 ft, a difference of 570 ft: hilly country. The highest named summit within 15 miles is Flat Top Mountain, about 10,580 ft, 9 miles north-northwest.
Under the town center the state geologic map shows Alluvium and colluvium (unconsolidated), from the Quaternary, less than 2.6 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 13 mi of the line.
Sandstone. Age: Carboniferous to Permian, 273 to 324 million years old. About 7 mi of the line.
Limestone. Age: Early Mississippian to Late Mississippian, 324 to 359 million years old. About 2 mi of the line.
Clay. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Basalt. Age: Pliocene, 2.6 to 5.3 million years old. About 0.7 mi of the line.
Mixed-clastic, coarse-detrital. Age: Middle Miocene to Late Pliocene, 2.6 to 16 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

Fairfield has a warm-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 13° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 12 inches of water.
On November 14 Fairfield normally reaches 53° and falls to 20°. The record high is 70°, in 1999; the record low −5°, in 1959. The most rain on this date, 0.56 in, fell in 1955.
