Glendale’s center stands about 530 ft above sea level. Within three miles the land runs from 370 ft to 1,570 ft, a difference of 1,200 ft: steep hill country. The highest named summit within 15 miles is San Gabriel Peak, about 6,120 ft, 11 miles northeast.
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 7 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.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 8 mi of the line.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 6 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Orthogneiss. Age: Paleoproterozoic to Miocene, 5.3 to 2,500 million years old. About 2 mi of the line.
Quartz-monzonite. Age: Late Triassic, 218 to 218 million years old. About 1 mi of the line.
Plutonic. Age: Jurassic to Cretaceous, 66 to 202 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Glendale reaches the Pacific Ocean by way of Verdugo Wash and the Los Angeles: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Glendale; river miles along the main stem, rounded.
Glendale has a hot semi-arid climate. Summer afternoons average 84° in August; winter nights fall to about 48° in December. About 14 inches of rain fall in a normal year.
On November 14 Glendale normally reaches 73° and falls to 54°. The record high is 93°, in 1933; the record low 36°, in 1880. The most rain on this date, 1.33 in, fell in 1928.
