73° on Nov. 14, 2016, the hottest reading for this week of the year since 1996. Next is 71° in 1999.
Lemmon Valley’s center stands about 4,990 ft above sea level. Within three miles the land runs from 4,910 ft to 5,880 ft, a difference of 970 ft: steep hill country. The highest named summit within 15 miles is Peavine Mountain, about 8,220 ft, 9 miles southwest.
Under the town center the state geologic map shows Playa, lake bed, and flood plain deposits (coarse-detrital, fine-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sedimentary, volcanic. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 6 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Granitic, granodiorite, quartz-monzonite. Age: Jurassic to Miocene, 5.3 to 202 million years old. About 5 mi of the line.
Metaandesite, metadacite, metarhyolite. Age: Triassic to Jurassic, 145 to 252 million years old. About 2 mi of the line.
Gravel, sand. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

Lemmon Valley has a cold semi-arid climate. Summer afternoons average 93° in July; winter nights fall to about 27° in December. A normal year brings about 30 inches of snow; with the rain, that comes to about 8 inches of water.
On November 14 Lemmon Valley normally reaches 55° and falls to 33°. The record high is 73°, in 2016; the record low 23°, in 2022. The most rain on this date, 0.08 in, fell in 2025.
Normals 1991–2020 and records since 1996 at Reno Wfo, 8 miles south-southeast. NOAA, through RCC-ACIS.
