4.50 inches of rain fell in two days, the most for this week of the year since records began in 1968. The next wettest, 1.27 inches, fell in 2020.
Stateline’s center stands about 6,290 ft above sea level. Within three miles the land runs from 6,220 ft to 9,300 ft, a difference of 3,080 ft: mountain country. The highest named summit within 15 miles is Freel Peak, about 10,840 ft, 8 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 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 5 mi of the line.
Granodiorite, granite. Age: Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 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 2 mi of the line.
Mafic-volcanic, felsic-volcanic. Age: Permian to Jurassic, 145 to 260 million years old. About 1 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 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. 3 smaller units along the line are not listed.

A raindrop that lands in Stateline reaches Pyramid Lake by way of Lake Tahoe and the Truckee: about 140 river miles. Pyramid Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Lake on the way: Lake Tahoe.
110 miles of the trip are on the Truckee.

Stateline has a dry-summer warm-summer continental climate. Summer afternoons average 80° in July; winter nights fall to about 18° in December. About 20 inches of rain fall in a normal year.
On November 14 Stateline normally reaches 52° and falls to 24°. The record high is 69°, in 2016; the record low 2°, in 1985. The most rain on this date, 0.37 in, fell in 2025.
