Richfield’s center stands about 5,360 ft above sea level. Within three miles the land runs from 5,250 ft to 6,720 ft, a difference of 1,470 ft: steep hill country. The highest named summit within 15 miles is Signal Peak, about 11,200 ft, 11 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 7 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.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 8 mi of the line.
Limestone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 8 mi of the line.
Felsic-volcanic. Age: Late Oligocene to Middle Miocene, 12 to 28 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 3 mi of the line.
Unconsolidated. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 2.6 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Richfield reaches Sevier Lake by way of the Sevier: about 240 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 Richfield; river miles along the main stem, rounded.
Richfield 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 Richfield 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.
