The Villa Park plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
95° on Nov. 13, 2007, the hottest reading for this week of the year since 1989. Next is 95° in 2016.
Villa Park’s center stands about 370 ft above sea level. Within three miles the land runs from 190 ft to 930 ft, a difference of 740 ft: hilly country. The highest named summit within 15 miles is Pleasants Peak, about 3,940 ft, 12 miles east.
Under the town center the state geologic map shows Older Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 7 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.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 12 mi of the line.
Sandstone, siltstone-mudstone. Age: Late Cretaceous, 66 to 100 million years old. About 5 mi of the line.
Argillite. Age: Paleozoic to Late Jurassic, 145 to 542 million years old. About 2 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone, conglomerate. Age: Middle Eocene to Early Miocene, 16 to 48 million years old. About 2 mi of the line.
Mudstone, sandstone. Age: Paleocene to Oligocene, 23 to 66 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Villa Park reaches the Pacific Ocean by way of the Santa Ana: about 14 river miles.
Often dry. About 70% 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 Villa Park; river miles along the main stem, rounded.
Villa Park has a hot semi-arid climate. Summer afternoons average 89° in August; winter nights fall to about 48° in December. About 14 inches of rain fall in a normal year.
On November 14 Villa Park normally reaches 77° and falls to 53°. The record high is 94°, in 2007; the record low 39°, in 2000. The most rain on this date, 0.86 in, fell in 2025.
