73° on Nov. 12, 1928, the hottest reading for this week of the year since 1893. Next is 71° in 1967.
Mayfield’s center stands about 5,530 ft above sea level. Within three miles the land runs from 5,300 ft to 6,890 ft, a difference of 1,590 ft: steep hill country. The highest named summit within 15 miles is Heliotrope Mountain, about 11,120 ft, 14 miles east.
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 3×. 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 11 mi of the line.
Limestone, mixed-clastic. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 5 mi of the line.
Siltstone-mudstone. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 3 mi of the line.
Mudstone. Age: Middle Jurassic, 164 to 175 million years old. About 2 mi of the line.
Sandstone. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 1 mi of the line.
Coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 0.7 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.

A raindrop that lands in Mayfield reaches Sevier Lake by way of Twelvemile Creek, the San Pitch and the Sevier: about 200 river miles. Sevier Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mayfield; river miles along the main stem, rounded.
Mayfield has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 18° in December. A normal year brings about 53 inches of snow; with the rain, that comes to about 13 inches of water.
On November 14 Mayfield normally reaches 51° and falls to 27°. The record high is 71°, in 1967; the record low 0°, in 1916. The most rain on this date, 0.55 in, fell in 1988.
