86° on Nov. 11, 1989, the hottest reading for this week of the year since 1944. Next is 86° in 1995.
Pearsonville’s center stands about 2,510 ft above sea level. Within three miles the land runs from 2,350 ft to 5,020 ft, a difference of 2,670 ft: mountain country. The highest named summit within 15 miles is Owens Peak, about 8,380 ft, 9 miles 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 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. 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. Age: Pleistocene to Holocene, less than 2.6 million years old. About 14 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 10 mi of the line.
Schist, gneiss. Age: Paleoproterozoic to Cretaceous, 66 to 2,500 million years old. About 0.1 mi of the line.

Rain that falls on Pearsonville runs only a short way, about 3 miles, to the desert basins of Owens Valley and Death Valley. The desert basins of Owens Valley and Death Valley 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 Pearsonville; river miles along the main stem, rounded.
Pearsonville has a hot desert climate. Summer afternoons average 105° in July; winter nights fall to about 30° in December. About 5 inches of rain fall in a normal year.
On November 14 Pearsonville normally reaches 70° and falls to 37°. The record high is 84°, in 2021; the record low 19°, in 1985. The most rain on this date, 0.44 in, fell in 1944.
Normals 1991–2020 and records since 1944 at China Lake Naf, 13 miles southeast, 280 ft lower. NOAA, through RCC-ACIS.
