"State investigators have determined that a Pacific Gas & Electric Co. power line was responsible for sparking last year’s massive Dixie fire, which torched more than 960,000 acres in five Northern California counties as it burned clear across the Sierra Nevada.
According to a statement by the California Department of Forestry and Fire Protection, investigators found that the fire “was caused by a tree contacting electrical distribution lines owned and operated by Pacific Gas & Electric located west of Cresta Dam.”
The department’s investigative report was forwarded to the Butte County district attorney’s office, according to Tuesday’s statement."
