82° on Nov. 17, 2020, the hottest reading for this week of the year since 1943. Next is 80° in 2021.
Wilkerson’s center stands about 4,530 ft above sea level. Within three miles the land runs from 3,990 ft to 8,920 ft, a difference of 4,930 ft: mountain country. The highest named summit within 15 miles is Polemonium Peak, about 14,080 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-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 2×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 7 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Sandstone, dolostone. Age: Neoproterozoic to Middle Devonian, 384 to 1,000 million years old. About 4 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Diorite, gabbro. Age: Triassic to Cretaceous, 66 to 252 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Wilkerson reaches Owens Lake by way of the Owens: about 85 river miles. Owens Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Often dry. About 40% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wilkerson; river miles along the main stem, rounded.
Wilkerson has a cold desert climate. Summer afternoons average 100° in July; winter nights fall to about 22° in December. About 5 inches of rain fall in a normal year.
On November 14 Wilkerson normally reaches 65° and falls to 27°. The record high is 79°, in 1967; the record low 16°, in 1994. The most rain on this date, 0.94 in, fell in 1981.
