The Logan Creek 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.
7° on Nov. 12, 2000, the coldest reading for this week of the year since 1988. Next is 8° in 1994.
Logan Creek’s center stands about 7,290 ft above sea level. Within three miles the land runs from 6,220 ft to 8,790 ft, a difference of 2,570 ft: mountain country. The highest named summit within 15 miles is Freel Peak, about 10,840 ft, 14 miles south.
Under the town center the state geologic map shows Felsic phaneritic intrusive rocks (granodiorite, granite), from the Cretaceous, 66 to 145 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. 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 6 mi of the line.
Metaandesite, metadacite, metarhyolite. Age: Triassic to Jurassic, 145 to 252 million years old. About 4 mi of the line.
Granodiorite, granite. Age: Cretaceous, 66 to 145 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 0.8 mi of the line.

A raindrop that lands in Logan Creek reaches Pyramid Lake by way of Logan House Creek and the Truckee: about 130 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.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Logan Creek; river miles along the main stem, rounded.
Logan Creek has a dry-summer warm-summer continental climate. Summer afternoons average 75° in July; winter nights fall to about 22° in December. About 22 inches of rain fall in a normal year.
On November 14 Logan Creek normally reaches 44° and falls to 28°. The record high is 60°, in 2016; the record low 15°, in 1993. The most rain on this date, 0.17 in, fell in 2006.
