100 years ago, almost to the day, a terrible fire wiped out 640 homes in Berkeley:
The 1923 Berkeley, California, fire was a conflagration that consumed some 640 structures, including 584 houses in the densely-built neighborhoods north of the campus of the University of California in Berkeley, California, on September 17, 1923.

Fires were breaking out all over California. Marin and Sonoma counties were hit hard.
In Marin, a wildfire on September 17 burned from Ignacio through Lucas and Nicasio Valleys, to Woodacre, Lagunitas, and Bolinas Ridge. This happened at the same time as huge fires burned in Sonoma County and in Berkeley, along with 15 other counties in California.

Read the front-page news from the September 19, 1923 San Francisco Examiner, below. Some commonalities in this story with what we have today are heat, wind, dry fuel, eucalyptus and other non-native trees and plants, above-ground electrical infrastructure and population density near forested land.
