3° on Nov. 14, 1985, the coldest reading for this week of the year since 1963. Next is 11° in 1964.
Hildale’s center stands about 5,040 ft above sea level. Within three miles the land runs from 4,900 ft to 7,030 ft, a difference of 2,130 ft: mountain country. The highest named summit within 15 miles is The West Temple, about 7,570 ft, 15 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 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Arenite, sandstone-mudstone. Age: Early Jurassic to Middle Jurassic, 164 to 202 million years old. About 8 mi of the line.
Sandstone. Age: Late Triassic to Early Jurassic, 180 to 210 million years old. About 7 mi of the line.
Mudstone. Age: Late Triassic, 210 to 230 million years old. About 5 mi of the line.
Mudstone. Age: Late Triassic, 202 to 237 million years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Hildale reaches the Gulf of California by way of Short Creek, Fort Pearce Wash, the Virgin and the Colorado: about 620 river miles.
Lakes on the way: Lake Mead, Lake Mohave and Lake Havasu.
290 miles of the trip are on the Colorado.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hildale; river miles along the main stem, rounded.
Hildale has a cold semi-arid climate. Summer afternoons average 94° in July; winter nights fall to about 22° in December. A normal year brings about 6 inches of snow; with the rain, that comes to about 11 inches of water.
On November 14 Hildale normally reaches 60° and falls to 30°. The record high is 77°, in 2025; the record low 3°, in 1985. The most rain on this date, 0.31 in, fell in 1978.
Normals 1991–2020 and records since 1963 at Pipe Spring National Monument, 16 miles southeast, 120 ft lower. NOAA, through RCC-ACIS.
