The Orovada plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
76° on Nov. 12, 2025, the hottest reading for this week of the year since 1911. Next is 74° in 1934.
Orovada’s center stands about 4,340 ft above sea level. Within three miles the land runs from 4,200 ft to 6,910 ft, a difference of 2,710 ft: mountain country. The highest named summit within 15 miles is Granite Peak, about 9,660 ft, 12 miles northeast.
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.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Granodiorite, granite. Age: Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Clastic. Age: Late Triassic to Middle Jurassic, 164 to 227 million years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Volcanic. Age: Miocene, 5.3 to 23 million years old. About 3 mi of the line.
Andesite, basalt. Age: Oligocene to Miocene, 5.3 to 34 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. 1 smaller unit along the line are not listed.

Orovada has a cold semi-arid climate. Summer afternoons average 94° in July; winter nights fall to about 18° in December. A normal year brings about 16 inches of snow; with the rain, that comes to about 10 inches of water.
On November 14 Orovada normally reaches 53° and falls to 24°. The record high is 73°, in 1999; the record low 4°, in 1985. The most rain on this date, 0.90 in, fell in 1957.
