CALIFORNIA – Thousands of firefighters battling a massive northern California wildfire were working in milder temperatures and higher humidity Monday, but the blaze that has destroyed more than 100 structures since it began five days ago continues to grow. The Park Fire, which officials said was started by a man who pushed a flaming car into a gully, grew slightly overnight to 368,000 acres (148,924 hectares). The sixth largest wildfire in state history is rolling through a remote area some 180 miles northeast of San Francisco, according to Cal Fire. Crews were “still in for quite a firefight, just because (of) the sheer magnitude and the sheer size of the fire,” said Dan Collins, a Cal Fire captain. …Some 4,800 firefighters were building and strengthening control lines on Monday morning hoping to increase the 12% they had contained.
