A Fresno County wildfire west of Coalinga grew larger but firefighters also increased containment, authorities said Friday.
The Mineral Fire expanded to more than 30 square miles and was 30% contained. Four structures have been destroyed and 60 remained threatened. No injuries were reported.
Evacuations encompassed the community of Bingham Springs and on various roads west to the Monterey County line.
The fire was burning in areas difficult to access and in vegetation with no fire history. Fire officials said extreme fire behavior, including rapid uphill and wind-driven runs, were hampering containment efforts.

The Fire Erupted Monday Afternoon

Eleven helicopters were assigned to the blaze and air tankers from around the state were flying fire suppression missions as conditions allowed.
The fire erupted Monday afternoon near Mineral Springs Road and State Route 198. It is in an area of Fresno County that has been abnormally dry for several months, according to the U.S. Drought Monitor.
