68° on Nov. 13, 1999, the hottest reading for this week of the year since 1895. Next is 61° in 1995.
Liberty Lake’s center stands about 2,080 ft above sea level. Within three miles the land runs from 2,010 ft to 3,290 ft, a difference of 1,280 ft: steep hill country. The highest named summit within 15 miles is Mica Peak, about 5,220 ft, 5 miles east-southeast.
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 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Argillite, siltstone. Age: Mesoproterozoic to Early Cambrian, 521 to 1,600 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 2 mi of the line.
Age: Paleoproterozoic, 1.9 to 1.9 billion years old. About 2 mi of the line.
Siltstone, sandstone. Age: Middle Miocene to Early Pliocene, 3.6 to 16 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.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Liberty Lake reaches the Pacific Ocean by way of the Spokane and the Columbia: about 720 river miles.
Lake on the way: Lake Umatilla.
360 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Liberty Lake; river miles along the main stem, rounded.
Liberty Lake has a dry-summer warm-summer continental climate. Summer afternoons average 83° in July; winter nights fall to about 26° in January. About 25 inches of rain fall in a normal year.
On November 14 Liberty Lake normally reaches 45° and falls to 32°. The record high is 63°, in 1999; the record low 0°, in 1955. The most rain on this date, 1.08 in, fell in 1937.
Normals 1991–2020 and records since 1895 at Coeur D'Alene, 14 miles east. NOAA, through RCC-ACIS.
