Monroe’s center stands about 5,420 ft above sea level. Within three miles the land runs from 5,300 ft to 7,680 ft, a difference of 2,380 ft: mountain country. The highest named summit within 15 miles is Monroe Peak, about 11,210 ft, 7 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 5 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.
Felsic-volcanic. Age: Late Oligocene to Middle Miocene, 12 to 28 million years old. About 15 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 7 mi of the line.
Conglomerate-sandstone. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 2 mi of the line.
Unconsolidated. Age: Pleistocene, less than 2.6 million years old. About 0.9 mi of the line.
Felsic-volcanic, andesite. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Monroe reaches Sevier Lake by way of the Sevier: about 250 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 Monroe; river miles along the main stem, rounded.
Monroe has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 16° in December. A normal year brings about 18 inches of snow; with the rain, that comes to about 8 inches of water.
On November 14 Monroe normally reaches 54° and falls to 24°. The record high is 74°, in 1967; the record low 5°, in 1916. The most rain on this date, 0.45 in, fell in 1991.
Normals 1991–2020 and records since 1893 at Richfield Radio Ksvc, 10 miles north-northeast, 140 ft lower. NOAA, through RCC-ACIS.
