The fire was completely extinguished about 11 p.m. Saturday night, a Cal Fire spokesman said. It was contained to a 50-foot-by-50-foot area.
A tree that had been smoldering since the Cuesta Fire burned south of Santa Margarita in August flared up on Saturday evening.
Cal Fire received a report of smoke at about 6:30 p.m. Saturday in an area east of Highway 101 and south of Highway 58. The fire was in a remote area that had previously burned in the Cuesta Fire, a Cal Fire dispatcher said.
Firefighters hiked to the spot to put out the new blaze, which burned about a 50-foot-by-50-foot area, the dispatcher said. The fire was expected to be fully controlled by midnight, she said.
The Cuesta Fire, which started Aug. 16, burned 2,446 acres and destroyed one building before being extinguished nearly two weeks later. At its height, 1,800 firefighters from around the state fought the blaze.
