Crews fight to outflank raging Northern California wildfire

Firefighters battled on Saturday to outflank a wildfire that has forced the closure of an interstate highway in Northern California as the blaze swept through explosively dry mountain timber in the Shasta-Trinity National Forest for a fourth day. As of midday Saturday, the Delta Fire had scorched nearly 37,000 acres (14,973 hectares) in the Cascade range since erupting on Wednesday in a forest canyon along the Sacramento River, about 250 miles (402 km) north of San Francisco, fire officials said. No serious injuries or deaths have been reported, but the blaze has caused major travel disruptions.
