A truck burst into flames, which spread to brush along Interstate 5 near Gorman on Sunday, fire officials said.
The fire began about 5:30 p.m., engulfing a truck towing what appeared to be a boat. Flames spread uphill, prompting firefighters to call in air support.
They quickly put out the blaze, which charred about 6 acres in the rugged area. The cause of the fire remained under investigation.
