1923 Berkeley, California, fire
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. == Course == Although the exact cause was never determined, the fire began in the undeveloped chaparral and grasslands of Wildcat Canyon, just east of the ridgeline of the Berkeley Hills, and was propelled over the ridge and southwestward just south of Codornices Creek by a strong, gusty, and intensely dry northeasterly wind.
