−3° on Nov. 13, 1916, the coldest reading for this week of the year since 1893. Next is 2° in 1955.
Fillmore’s center stands about 5,130 ft above sea level. Within three miles the land runs from 4,880 ft to 5,790 ft, a difference of 910 ft: steep hill country. The highest named summit within 15 miles is Mine Camp Peak, about 10,200 ft, 8 miles south-southeast.
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 9 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 14 mi of the line.
Arenite. Age: Early Cambrian to Middle Cambrian, 497 to 542 million years old. About 3 mi of the line.
Siltstone-mudstone, sandstone. Age: Late Cretaceous to Early Eocene, 48 to 84 million years old. About 2 mi of the line.
Mixed-clastic, coarse-detrital. Age: Middle Miocene to Late Pliocene, 2.6 to 16 million years old. About 1 mi of the line.
Basalt. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.
Dolostone, limestone. Age: Middle Cambrian, 497 to 521 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 3 smaller units along the line are not listed.

A raindrop that lands in Fillmore reaches Sevier Lake by way of the Central Utah Canal and the Sevier: about 150 river miles. Sevier Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
100 miles of the trip are on the Sevier.
Often dry. About 30% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fillmore; river miles along the main stem, rounded.
Fillmore has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 21° in January. A normal year brings about 62 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 Fillmore normally reaches 50° and falls to 29°. The record high is 81°, in 1906; the record low 3°, in 1916. The most rain on this date, 0.85 in, fell in 1988.
