To the south, firefighters made progress containing a huge blaze in mountains outside Los Angeles, allowing authorities to let most of 20,000 people evacuated over the weekend to return home. In Wyoming, a large backcountry wildfire in the Shoshone National Forest put about 290 homes and guest ranches at risk.
The Los Angeles-area fire has destroyed 18 homes since it started and authorities over the weekend discovered a burned body in a car identified yesterday as a man who refused to be evacuated.
The Big Sur closures were put into place for parks that draw 7,500 visitors daily from around the world for their dramatic vistas of ocean and mountains along Highway 1 near storied Monterey Bay.
The park shutdowns came as a fire that started on Friday just north of Big Sur grew yesterday to 78 square kilometres but was just 10 percent contained. Twenty homes have burned in the zone, residents of 300 more were ordered to evacuate and more than 2,000 firefighters were trying to douse the blaze.
Park roads, trails and camping sites in five parks and a nature reserve were closed as a safety precaution because of thick smoke causing unhealthy air quality and to keep the roads free of traffic for firefighters, said state parks spokesman Dennis Weber.
