IDYLLWILD, Calif. -- A fast-moving wildfire -- believed to have been sparked by arson -- tore through trees, burned five homes and forced evacuation orders for an entire forest town as California. The state is battling ferocious fires at both ends of the state.
The so-called Cranston Fire, which erupted Wednesday in the San Jacinto Mountains east of Los Angeles, turned into a wall of flames that torched timber and tinder-dry brush. In a matter of hours it grew to 7.5 square miles. It was threatening an estimated 600 homes, authorities said.
The fire was the largest of at least five that police believe were purposely set Wednesday by a man whose car was reportedly spotted at the starting point of the blaze in Riverside County, officials said. Brandon N. McGlover, 32, of Temecula was booked on suspicion of five counts of arson, state fire officials said. It wasn't clear whether he had an attorney.
Authorities ordered residents to leave Idyllwild and several neighboring communities, home to about 12,000 people. CBS affiliate KFMB-TV reported that the Riverside Sheriff's station was conducting evacuations of Idyllwild, the Apple Canyon area, the Lake Hemet area, Mountain Center Community, the Hurkey Creek area and Camp Scherman Girl Scout Camp.
William Blodgett of Idyllwild said he couldn't get home because of the fire and had to wait along with others at a gas station in nearby Mountain Center -- until the fire hopped a highway and began to move in his direction.
"We were all peeling out of there as fast as we could," he told KNBC-TV. "It was apocalyptic."
Horses and other animals were taken to shelters as were several hundred children who were evacuated from summer camps. About 200 were at a local high school serving as a shelter, KCAL-TV reported.
The fire in the San Bernardino National Forest sent up a cloud 50,000 feet high that was so enormous it created its own weather in the form of lightning, the National Weather Service reported. Throughout the day, helicopters and planes dumped water and fire retardant that turned swathes of land and homes pink. Fire engines also were stationed to protect homes.
The fire is one of several across California amid a heat wave that has seen days of triple-digit temperatures. To the north, in the San Francisco Bay Area, at least one home burned in a fast-moving blaze in Clayton, where houses are spread out around windy roads.
Dry grass and brush in steep terrain was fueling the blaze, according to Cal Fire officials. It prompted a large regional response, including 180 personnel from agencies such as the Contra Costa County Fire Protections District among other local agencies, CBS SF BayArea reported.
Yosemite Valley, the scenic heart of the national park, wasduring the height of tourist season as smoke cast a pall on the region from a fire in the Sierra Nevada. The closure was heartbreaking for travelers, many of whom mapped out their trips months in advance to hike and climb amid the spectacular views of cascading waterfalls and sheer rock faces.
"We had one guest who planned a weeklong trip," said Tom Lambert, who owns a vacation rental property near Yosemite Valley. "It was a father-daughter trip, for her high school graduation ... Now it's done. It's sad." Another guest had to delay plans to climb Half Dome.
Officials emphasized that Yosemite wasn't in imminent danger from the fire. Authorities decided on the shutdown to allow crews to perform protective measures such as burning away brush along roadways without having to deal with traffic in the park that welcomes 4 million visitors annually.
Yosemite Valley will be closed until at least Sunday, along with a winding, mountainous, 20-mile stretch of California's State Route 41 that leads into the area, Gediman said.
"Thank you for your understanding and for your support of the 3,400 firefighters hard at work protecting our park," the park tweeted Thursday.
At least 1,000 campground and hotel bookings were canceled -- to say nothing of the impact on day visitors, park workers and small businesses along the highway, Gediman said.
The last time the 7.5-mile-long valley was closed because of fire was 1990, he said.
Over nearly two weeks, flames have churned through 60 square miles of timber in steep terrain of the Sierra Nevada just west of the park. The fire was just 25 percent contained.
More than 3,300 firefighters are working the fire, aided by 16 helicopters. One firefighter was killed July 14, and six others have been injured.
In the state's far north, a 7-square-mile wildfire has forced the evacuation of French Gulch, a small Shasta County community that dates to the Gold Rush.
