5° on Nov. 14, 1916, the coldest reading for this week of the year since 1896. Next is 8° in 1924.
Mina’s center stands about 4,570 ft above sea level. Within three miles the land runs from 4,520 ft to 5,630 ft, a difference of 1,110 ft: steep hill country. The highest named summit within 15 miles is Pilot Peak, about 9,130 ft, 8 miles east-southeast.
Under the town center the state geologic map shows Alluvium, undifferentiated (coarse-detrital, fine-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 9 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 7 mi of the line.
Clastic, volcanic. Age: Late Devonian to Permian, 252 to 384 million years old. About 4 mi of the line.
Carbonate, arenite, clastic. Age: Middle Triassic to Middle Jurassic, 164 to 247 million years old. About 4 mi of the line.
Sandstone, volcanic. Age: Late Triassic to Early Jurassic, 175 to 237 million years old. About 3 mi of the line.
Granodiorite, granite. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Carbonate, clastic, arenite. Age: Middle Triassic to Middle Jurassic, 164 to 247 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. 3 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
Rain that falls on Mina runs straight into the Great Basin. The Great Basin 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 Mina; river miles along the main stem, rounded.
Mina has a cold desert climate. Summer afternoons average 97° in July; winter nights fall to about 26° in December. A normal year brings about 8 inches of snow; with the rain, that comes to about 6 inches of water.
On November 14 Mina normally reaches 59° and falls to 34°. The record high is 75°, in 1904; the record low 5°, in 1916. The most rain on this date, 0.22 in, fell in 1997.
