73° on Nov. 12, 1996, the hottest reading for this week of the year since 1948. Next is 66° in 1959.
Keno’s center stands about 4,110 ft above sea level. Within three miles the land runs from 4,060 ft to 5,160 ft, a difference of 1,100 ft: steep hill country. The highest named summit within 15 miles is Little Aspen Butte, about 7,240 ft, 13 miles northwest.
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 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 12 mi of the line.
Basaltic-andesite, basalt. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Andesite, basalt. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 1 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 years old. About 0.9 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 Keno reaches the Pacific Ocean by way of the Klamath: about 240 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Keno; river miles along the main stem, rounded.
Keno has a cold semi-arid climate. Summer afternoons average 86° in July; winter nights fall to about 20° in December. About 11 inches of rain fall in a normal year.
On November 14 Keno normally reaches 50° and falls to 25°. The record high is 62°, in 2021; the record low 1°, in 1985. The most rain on this date, 0.45 in, fell in 1968.
Normals 1991–2020 and records since 1948 at Klamath Falls Ag Sta, 9 miles east-northeast. NOAA, through RCC-ACIS.
