CRESTLINE, Calif. (AP) — Smoke plumes roiling from flaming ridges of the San Bernardino Mountains threatened thousands of homes and blew all the way across the Mojave Desert to Las Vegas as California’s latest big wildfire chewed through timber and brush Monday.
Hundreds of firefighters, aided by 16 aircraft, battled flames that spread across nearly 10 square miles on the northern side of the rugged mountain range east of Los Angeles.
Dozens of homes were ordered evacuated, and authorities recommended voluntary evacuations for more than 5,000.
Helicopters sucked loads of water from nearby Silverwood Lake to douse flames leaping across slopes. Air tankers swooped low to paint the dry vegetation with pink fire retardant.
The fire, which erupted for an unknown reason Sunday, was just 6 percent contained.
Across the Mojave, officials in southern Nevada issued an air quality advisory because of smoke from the fire more than 200 miles away.
The Clark County Department of Air Quality said the air was unhealthy for sensitive groups, including young children, senior citizens and people with respiratory problems and cardiac disease.
Like some of the state’s other fires this summer, the blaze burned near a popular recreation area. But Silverwood Lake’s waters had been closed to swimming, fishing and boating since Aug. 4 because of an algae bloom.
About 5,200 homes were under either mandatory or voluntary evacuations, but it wasn’t immediately clear how many were in each category.
On the central coast, meanwhile, California’s biggest fire expanded to more than 94 square miles north of scenic Big Sur. An army of more than 5,000 firefighters and an air force of tankers and helicopters made progress, however, surrounding 45 percent of the 18-day-old blaze.
Firefighters set fires to burn out vegetation between the main body of the fire and prepared control lines.
Long-suffering residents of Palo Colorado who had been under evacuation orders since late July were finally being allowed to return. Some evacuation orders remained in place, while others were reduced to warnings.
Five state parks on Highway 1 between San Francisco and Los Angeles remained closed.
The fire, which has destroyed 57 homes, damaged three others and led to the death of a bulldozer operator in an accident, was caused by an illegal campfire.
