Humid weather has slowed the spread of the so-called Eagle Fire, which has burned 12,700 acres with 45 percent containment as of late Monday afternoon, but six firefighters have sustained minor injuries from working in the conditions, according to Cal Fire.
More than 2,100 firefighters are working the fire located off of Highway 79 near Warner Springs, and National Guard helicopters are helping fly hand crews into remote areas.
The costs associated with the blaze jumped from an estimated $2.5 million Sunday to $6.2 million by 6 p.m. Monday. Seventy-one engines, 85 fire crews, 20 bulldozers, 30 water tenders, 17 helicopters, five helitankers, six airtankers and 274 overhead have all been assigned to assist.
The fire, reported at 10:40 p.m. Thursday, is said to be burning in a mix of grass, brush, oak and pine trees in steep, rugged terrain on the Los Coyotes Indian Reservation and the Anza Borrego Desert State Park.
Officials said it is moving toward the northwest and is visible from the desert community of Borrego Springs.
The Borrego Palm Canyon Trail and Campground in the Anza Borrego Desert State Park have been closed due to the flames.
Sunday there were reports of two injured firefighters, who were both transported to a hospital and treated for minor injuries. Their injuries were not immediately known.
Friday, officials said two cabins and a number of archeological sites were threatened ending in an evacuation, though only one outbuilding has been destroyed.
