−11° on Nov. 15, 1955, the coldest reading for this week of the year since 1888. Next is −10° in 1909.
Osino’s center stands about 5,130 ft above sea level. Within three miles the land runs from 5,110 ft to 7,010 ft, a difference of 1,900 ft: steep hill country. The highest named summit within 15 miles is Elko Mountain, about 7,470 ft, 3 miles south-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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. 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 10 mi of the line.
Shale, siltstone, sandstone. Age: Early Mississippian to Middle Pennsylvanian, 307 to 359 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 3 mi of the line.
Rhyolite, dacite. Age: Middle Eocene to Early Oligocene, 28 to 48 million years old. About 3 mi of the line.
Sandstone, siltstone, limestone. Age: Permian, 252 to 299 million years old. About 0.9 mi of the line.
Siltstone, limestone, shale. Age: Late Devonian to Early Mississippian, 347 to 384 million years old. About 0.5 mi of the line.

A raindrop that lands in Osino reaches the Great Basin by way of the Humboldt: about 400 river miles. 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 Osino; river miles along the main stem, rounded.
Osino has a cold semi-arid climate. Summer afternoons average 92° in July; winter nights fall to about 15° in December. A normal year brings about 41 inches of snow; with the rain, that comes to about 10 inches of water.
On November 14 Osino normally reaches 51° and falls to 22°. The record high is 70°, in 2016; the record low −7°, in 1955. The most rain on this date, 1.05 in, fell in 1930.
