The deadly California wildfires have burned over 1 million acres -- and there's no end in sight as thousands of firefighters struggle to contain the blazes and more emerge. Hundreds of fires were started by lightning, Cal Fire spokesman Steve Kaufmann said.

There were approximately 12,000 lightning strikes that started 585 fires in the state over the past week. A total of 1.1 million have burned in the state with more than 13,000 firefighters working the fires, he said. Firefighters have been struggling to contain the massive blazes that have killed at least four people. Two fires -- the 347,630 -acre LNU Lightning Complex Fire in the northern Bay Area and Central Valley, and the 343,965 acre-acre SCU Lightning Complex Fire largely east of San Jose -- are among the state's three largest wildfires in recorded history.
