70° on Nov. 12, 1967, the hottest reading for this week of the year since 1904. Next is 70° in 1973.
Riverton’s center stands about 4,440 ft above sea level. Within three miles the land runs from 4,320 ft to 4,680 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Twin Peaks, about 11,430 ft, 15 miles east.
Under the town center the state geologic map shows Lake Bonneville deposits (clay), from the Pleistocene, 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.
Clay. Age: Pleistocene, less than 2.6 million years old. About 10 mi of the line.
Granodiorite. Age: Middle Eocene to Early Oligocene, 30 to 42 million years old. About 6 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 3 mi of the line.
Coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous to Permian, 273 to 324 million years old. About 2 mi of the line.
Latite, quartz-latite. Age: Late Eocene to Oligocene, 23 to 38 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 Riverton reaches Great Salt Lake by way of the Jordan: about 35 river miles. Great Salt 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 Riverton; river miles along the main stem, rounded.
Riverton has a cold semi-arid climate. Summer afternoons average 92° in July; winter nights fall to about 19° in January. A normal year brings about 26 inches of snow; with the rain, that comes to about 13 inches of water.
On November 14 Riverton normally reaches 49° and falls to 27°. The record high is 67°, in 1967; the record low 3°, in 1956. The most rain on this date, 0.68 in, fell in 1987.
Normals 1991–2020 and records since 1904 at Utah Lake Lehi, 11 miles south. NOAA, through RCC-ACIS.
