20° on Nov. 14, 1916, the coldest reading for this week of the year since 1893. Next is 22° in 1911.
El Macero’s center stands about 40 ft above sea level. Within three miles the land runs from 10 ft to 60 ft, a difference of 50 ft: nearly flat ground.
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 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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 24 mi of the line.
Sandstone, conglomerate. Age: Miocene to Pleistocene, less than 23 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 El Macero reaches San Francisco Bay and the Pacific Ocean by way of Prospect Slough, Cache Slough and the Sacramento: about 40 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of El Macero; river miles along the main stem, rounded.
El Macero has a hot-summer Mediterranean climate. Summer afternoons average 93° in July; winter nights fall to about 38° in January. About 19 inches of rain fall in a normal year.
On November 14 El Macero normally reaches 66° and falls to 43°. The record high is 83°, in 1894; the record low 20°, in 1916. The most rain on this date, 1.72 in, fell in 1981.
Normals 1991–2020 and records since 1893 at Davis 2 WSW Experiment Farm, 5 miles west. NOAA, through RCC-ACIS.
