−4° on Nov. 16, 1955, the coldest reading for this week of the year since 1908. Next is −3° in 1911.
Moroni’s center stands about 5,580 ft above sea level. Within three miles the land runs from 5,490 ft to 5,970 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is North Tent Mountain, about 11,190 ft, 14 miles 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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. 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, mudstone, conglomerate. Age: Early Cretaceous to Late Cretaceous, 72 to 113 million years old. About 6 mi of the line.
Siltstone-mudstone. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 3 mi of the line.
Shale, marlstone. Age: Early Eocene to Late Eocene, 34 to 56 million years old. About 0.9 mi of the line.
Sandstone. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 0.8 mi of the line.
Mudstone. Age: Middle Jurassic, 164 to 175 million years old. About 0.3 mi of the line.

A raindrop that lands in Moroni reaches Sevier Lake by way of the San Pitch and the Sevier: about 230 river miles. Sevier Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
180 miles of the trip are on the Sevier.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Moroni; river miles along the main stem, rounded.
Moroni has a warm-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 13° in January. About 12 inches of rain fall in a normal year.
On November 14 Moroni normally reaches 53° and falls to 22°. The record high is 72°, in 1967; the record low 7°, in 1994. The most rain on this date, 0.72 in, fell in 1988.
