95° on Nov. 16, 2020, the hottest reading for this week of the year since 1923. Next is 95° in 2021.
Casa Conejo’s center stands about 660 ft above sea level. Within three miles the land runs from 150 ft to 1,520 ft, a difference of 1,370 ft: steep hill country. The highest named summit within 15 miles is Sandstone Peak, about 3,020 ft, 4 miles south.
Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
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 7×. 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 to Holocene, less than 2.6 million years old. About 6 mi of the line.
Basalt, andesite. Age: Late Oligocene to Late Miocene, 8 to 25 million years old. About 6 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 5 mi of the line.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 0.9 mi of the line.
Sandstone, conglomerate. Age: Middle Eocene to Early Miocene, 16 to 48 million 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. 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 Casa Conejo reaches the Pacific Ocean by way of the South Branch Arroyo Conejo, the Arroyo Conejo, Conejo Creek and Calleguas Creek: about 25 river miles.
Often dry. About 100% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Casa Conejo; river miles along the main stem, rounded.
Casa Conejo has a cold semi-arid climate. Summer afternoons average 80° in August; winter nights fall to about 44° in December. About 12 inches of rain fall in a normal year.
On November 14 Casa Conejo normally reaches 73° and falls to 49°. The record high is 94°, in 1949; the record low 34°, in 2000. The most rain on this date, 1.63 in, fell in 1953.
Normals 1991–2020 and records since 1923 from the Camarillo Area threaded record (Camarillo Airport, 8 miles west-northwest, 590 ft lower). NOAA, through RCC-ACIS.
