The Laguna Fire, previously known as the Kitchen Creek Fire and the Boulder Oaks Fire, occurred in 1970 in eastern San Diego County, California of Southern California. It was the third largest wildfire in the history of California at that time, after the Santiago Canyon Fire of 1889 and the Matilija Fire of 1932. It was one of many wildfires in a massive conflagration that spanned across the state from September 22—October 4, 1970.
