Dixie, other wildfires advance through Northern California

Houses reduced to smouldering ash and twisted metal with only chimneys rising above the ruins.

Northern California wildfires that incinerated two communities continue marching through the Sierra Nevada mountains on Wednesday while an electricity company cut power to 51,000 customers to prevent new blazes on Tuesday. Two weeks after the Dixie Fire destroyed most of the Gold Rush-era town of Greenville, the Caldor Fire a few miles southeast exploded through tinder-dry trees and ravaged Grizzly Flats, a forest community of approximately 1,200 people. Fire officials estimated that at least 50 homes had burned in the area since the fire erupted Saturday and two people were hospitalised with serious injuries.
