71° on Nov. 12, 1999, the hottest reading for this week of the year since 1951. Next is 66° in 1990.
Camas’s center stands about 2,820 ft above sea level. Within three miles the land runs from 2,750 ft to 4,130 ft, a difference of 1,380 ft: steep hill country. The highest named summit within 15 miles is Baldy Mountain, about 7,460 ft, 8 miles west.
Under the town center the state geologic map shows Glacial deposit (unconsolidated), from the Pleistocene to Holocene, less than 1.8 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.
Quartzite, argillite, metasiltstone. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 12 mi of the line.
Silt, sand, clay. Age: Pleistocene to Holocene, less than 1.8 million years old. About 6 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 1.8 million years old. About 2 mi of the line.
Metasiltstone, argillite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Metasiltstone, argillite, quartzite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Quartzite, metasiltstone, argillite. Age: Mesoproterozoic, 1 to 1.6 billion 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. 2 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 Camas reaches the Pacific Ocean by way of Hot Springs Creek, the Little Bitterroot, the Flathead, the Clark Fork, the Pend Oreille and the Columbia: about 1,040 river miles.
Lakes on the way: Lake Pend Oreille, Lake Umatilla and Noxon Rapids Reservoir.
460 miles of the trip are on the Columbia.

Camas has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 20° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 16 inches of water.
On November 14 Camas normally reaches 40° and falls to 26°. The record high is 62°, in 1990; the record low −4°, in 1959. The most rain on this date, 0.38 in, fell in 2021.
Normals 1991–2020 and records since 1951 at Skq Dam, 20 miles east-northeast. NOAA, through RCC-ACIS.
