Firefighters are battling a 550-acre fire in rugged and remote eastern San Diego County.

The California Department of Forestry and Fire Protection says the blaze began at 12:20 p.m. Thursday north of State Route 79, east of the town of Julian.

The blaze is 30 percent contained, and no injuries or structure damage has been reported.

State fire officials announced a controlled burn earlier in the day near the fire, but it was unclear if the two blazes were linked.

Elsewhere, Los Angeles County firefighters made quick work of a fire that spread rapidly up a slope within sight of homes in Santa Clarita.

Ground crews and water-dropping helicopters attacked the 1:10 p.m. blaze and fully contained it at five acres about an hour later.
