76° on Nov. 15, 2016, the hottest reading for this week of the year since 1893. Next is 75° in 1999.
Levan’s center stands about 5,330 ft above sea level. Within three miles the land runs from 5,150 ft to 7,410 ft, a difference of 2,260 ft: mountain country. The highest named summit within 15 miles is Salt Creek Peak, about 9,960 ft, 10 miles northeast.
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 10 mi of the line.
Sandstone, mudstone, conglomerate. Age: Early Cretaceous to Late Cretaceous, 72 to 113 million years old. About 5 mi of the line.
Peat. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Latite, quartz-latite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 2 mi of the line.
Sandstone. Age: Late Eocene to Early Oligocene, 28 to 38 million years old. About 2 mi of the line.
Mudstone. Age: Middle Jurassic, 164 to 175 million years old. About 0.9 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 Levan reaches Sevier Lake by way of Chicken Creek 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.
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 Levan; river miles along the main stem, rounded.
Levan has a hot-summer humid continental climate. Summer afternoons average 91° in July; winter nights fall to about 18° in January. A normal year brings about 32 inches of snow; with the rain, that comes to about 14 inches of water.
On November 14 Levan normally reaches 52° and falls to 27°. The record high is 74°, in 1990; the record low −2°, in 1916. The most rain on this date, 1.42 in, fell in 1917.
