1970 - A nineteen month drought in southern California came to a climax. The drought, which made brush and buildings tinder dry, set up the worst fire conditions in California history as hot Santa Anna winds sent the temperature soaring to 105 degrees at Los Angeles, and to 97 degrees at San Diego. During that last week of September whole communities of interior San Diego County were consumed by fire. Half a million acres were burned, and the fires caused fifty million dollars damage.
