Two Southern California wildfires torched dozens of mountain homes, tore through a ski resort, and forced thousands to evacuate in towns and cities east of Los Angeles.

Around 40 homes and cabins burned in the villages of Mount Baldy and Wrightwood, and flames swept through the nearby Mountain High ski resort in San Bernardino County, the Los Angeles Fire Department reported.

The blaze, named the Bridge Fire, exploded to more than 48,000 acres, becoming the largest in the state and one of four burning within sight of each other. The Southern California fires have blackened 105,000-plus acres of scrub, brush, and forest, an area a third the size of Los Angeles.

The Airport Fire in Orange and Riverside counties destroyed dozens of homes in El Cariso Village and Decker Canyon as it grew to more than 22,000 acres, according to authorities and local news reports.
