Firefighters are working Wednesday to subdue a wildfire that has spread over about 1,300 open acres in the rural southeastern reaches of San Diego County.
As of 7 a.m. Wednesday, the fire consumed 1,362 acres and was 50% contained.
The blaze erupted at about 3:30 p.m. Monday when a car overturned and caught fire on Interstate 8 near McCain Valley Road in Boulevard, north of Jacumba Hot Springs, according to Cal Fire.
The flames spread into rugged, rocky, brush-covered terrain on the north side of the freeway, moving toward nearby De Anza Springs Resort, said Mike Cornette, a fire captain with the state agency.
As firefighters battled the blaze on the ground and aboard air tankers and water-dropping helicopters, authorities closed the westbound lanes of the freeway in the area and cleared a total of 144 people out of threatened homes, most of them on the grounds of the resort on Carrizo Gorge Road, Cornette said.
A temporary shelter for the evacuees was in operation at Golden Acorn Casino in Campo. That closed Wednesday at 7 a.m.
As of Wednesday afternoon, the San Diego Sheriff's Department had lifted all evacuation warnings and road closures in Boulevard.
As of midday Tuesday, the fire had caused no reported structural damage, though it had moved to within less than a mile of some residences.
The only known injuries stemming from the emergency were suffered by the motorist involved in the crash that sparked the blaze. Medics took that person to a hospital for treatment of moderately serious trauma, Cornette said.
In the mid-afternoon Tuesday, authorities rescinded the evacuation order pertaining to De Anza Springs Resort, though residents near the burn zone were advised to remain ready to clear out of their neighborhoods should the fire become an imminent threat again.
The fire prompted a smoke advisory for the southeastern reaches of the San Diego area, the county Air Pollution Control District advised.
Among the threats posed by the conflagration involved potential damage to historic and culturally significant Native American artifacts, including wall art, according to Cal Fire. It remained unclear Tuesday afternoon whether any of the antiquities had been harmed by the blaze.
There were 223 firefighter personnel, four helicopters and 14 engines assigned to battle the fire on Tuesday.
According to Cal Fire, the fire was not as active Tuesday compared to Monday and gave firefighters a chance to increase the containment percentage from 5% to 30%.
