Cal Fire Determines Cause of Massive Rocky Fire

The now contained blaze is the largest this year and fifth largest since 2010.

Cal Fire announced Wednesday that a faulty gas water heater was the ignition source of the fire. It had been located in an outbuilding which housed flammable liquid.

Overall, the fire burned just shy of 70,000 acres across Lake, Yolo, and Colusa counties. Earlier this month it also merged with the Jerusalem Fire, which at the time of writing is 95% contained with over 25,000 acres burned.

Over the two weeks that the Rocky Fire was active, it forced the evacuation of approximately 13,000 people and closure of local highways. Governor Jerry Brown visited the fire area and while citing climate change said that the Rocky Fire and other like it represented a “new normal.”
