The June Lake plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
72° on Nov. 11, 2014, the hottest reading for this week of the year since 1988. Next is 71° in 2016.
June Lake’s center stands about 7,340 ft above sea level. Within three miles the land runs from 7,220 ft to 11,020 ft, a difference of 3,800 ft: mountain country. The highest named summit within 15 miles is Mount Ritter, about 13,020 ft, 7 miles southwest.
Under the town center the state geologic map shows Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges) (granodiorite), from the Permian to Tertiary, 2.6 to 260 million years old.
The section below crosses 8 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. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Chert, argillite. Age: Ordovician to Devonian, 359 to 487 million years old. About 5 mi of the line.
Rhyolite. Age: Pleistocene to Holocene, less than 2.6 million years old. About 4 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 3 mi of the line.
Rhyolite. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 2 mi of the line.
Basanite. Age: Early Pliocene to Late Pliocene, 3 to 4 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. 2 smaller units along the line are not listed.

A raindrop that lands in June Lake reaches Mono Lake by way of Reversed Creek and Rush Creek: about 17 river miles. Mono Lake 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 June Lake; river miles along the main stem, rounded.
June Lake has a dry-summer warm-summer continental climate. Summer afternoons average 84° in July; winter nights fall to about 20° in January. A normal year brings about 70 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 June Lake normally reaches 54° and falls to 28°. The record high is 66°, in 1990; the record low 17°, in 2022. The most rain on this date, 0.85 in, fell in 2025.
Normals 1991–2020 and records since 1988 at Lee Vining, 13 miles north, 540 ft lower. NOAA, through RCC-ACIS.
