CAL Fire determined that the Eagle Fire in east county San Diego was a result of arson.
The fire was 75 percent contained across 14,100 acres as of Thursday morning. CAL Fire said the fire’s spread to the east has slowed considerably they it is hoping to extinguish the fire by Saturday.
An update from CAL Fire stated that "Firefighters remain vigilant, faced with warm temperatures and low humidity," and that they are now beginning to mitigate the effects that the fire control has had on the land.
One structure was destroyed and 12 people sustained injuries. No evacuations or road closures were ordered in the remote area.
More than 50 fire engines were on the scene Thursday morning -- about 20 fewer than were present Wednesday. There were also 20 helicopters, 83 fire crews, seven air tankers, 18 bulldozers and more than 2,000 personnel working to contain the fire Thursday.
The fire has burned 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. The fire continues to burn towards the east and the northwest.
The northern portion continues to burn in heavy vegetation through an area with no known fire history. Afternoon winds are expected to push smoke into the eastern Coachella Valley and the community of Borrego Springs.
The Borrego Palm Canyon Campground and Trail remain closed, along with the Lost Valley Boy Scout Camp.
