Southern California's big wildfire continues to grow.
The fire command says the destructive blaze has scorched more than 49 square miles as of Thursday morning, up from 40 square miles Wednesday night.
Firefighters continue to battle flames that have climbed the rugged flanks of the San Gabriel Mountains, threatening communities including the ski town of Wrightwood at an elevation of nearly 6,000 feet.
The fire erupted Tuesday morning in Cajon Pass, 60 miles east of Los Angeles, and spread rapidly.
Firefighters have yet to tally property losses but indicate there have been many.
Meanwhile, the 15 through Cajon Pass has reopened.
However, off-ramps through the affected areas are to remain closed as crews continue to battle the blaze.
