More than 1,700 firefighters are still battling a 11,000-acre brush fire Monday in northeastern San Diego County, authorities said.
The Eagle Fire, which was burning on the Los Coyotes Indian Reservation and Anza Borrego Desert State Park, broke out about five miles east of Warner Springs Thursday night. It was about 40 percent contained as of Sunday evening, according to Cal Fire.
The cause of the blaze remains under investigation.
Five firefighters suffered minor injuries and one outbuilding has burned since the fire broke out. An estimated $4.5 million has been spent battling it so far, the state agency reported.
California National Guard helicopters joined the fight Sunday, helping to shuttle firefighters to remote areas as flames moved northwest toward Borrego Springs.
Agencies assisting Cal Fire with staff, equipment and other resources included: The San Diego County Fire Authority; U.S. Forest Service; Bureau of Indian Affairs; San Diego County Sheriff's Department; California Department of Parks and Recreation; California Conservation Corps; and California Department of Corrections and Rehabilitation.
The Borrego Palm Canyon Campground and Trail have been closed, along with the Los Valley Boy Scout Camp.
