The heart of Yosemite National Park, where throngs of tourists are awe-struck by cascading waterfalls and towering granite features like El Capitan and Half Dome, will be closed as firefighters try to corral a huge wildfire just to the west that has cast a smoky pall and threatened the park's forest, officials said Tuesday.
Yosemite Valley will be closed for at least four days beginning at noon Wednesday, along with a winding, mountainous, 20-mile stretch of State Route 41, park spokesman Scott Gediman said.
At least a thousand campground and hotel bookings will be canceled – to say nothing of the impact on day visitors, park workers, and small businesses along the highway, Mr. Gediman said. Rangers were going to campsites one at a time to inform visitors of the closures. Hotels guests were getting phone calls and notes on their doors.
"We're asking people here tonight to leave tomorrow morning," he said, adding that many people have already left. "And anyone that's incoming tomorrow will get an email or phone call stating that their reservation is canceled."
The last time the 7.5-mile-long valley was closed because of fire was 1990, he said.
Officials were quick to point out that Yosemite wasn't under imminent danger from the Ferguson Fire. Authorities decided on the closure 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 is the centerpiece of the visitor experience, offering views of landmarks such as Half Dome, Sentinel Dome, Bridal Veil Fall, El Capitan, and Yosemite Falls. The glacial valley's grand vista of waterfalls and shear granite faces has been obscured by a choking haze of smoke from the Ferguson Fire.
Visitors are advised to "limit activity during the periods of poor air quality," the park said in a statement. "Some facilities and services are closed or diminished."
Over nearly two weeks, flames have churned through more than 57 square miles of timber in steep terrain of the Sierra Nevada just west of the park. The fire was just 25 percent contained Tuesday morning.
Mandatory evacuations are in place in several communities while others have been told to get ready to leave if necessary.
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.
Rhonda Salisbury, CEO of Visit Yosemite/Madera County, said the regional visitors bureau has been relocating tourists statewide following the closure.
"People are heartbroken," she said. "Some want to ride it out for a few days and see if they can get back in the park." Others want help finding places to stay away from Yosemite.
Gediman suggested valley visitors divert to Tuolumne Meadows, on Yosemite's northern edge, or to Sequoia and Kings Canyon National Parks to the south.
"There are wonderful places to visit in the region, so we're asking people to consider alternative plans," he said.
In the state's far north, a nearly 4-square-mile wildfire has forced the evacuation of French Gulch, a small Shasta County community that dates to the Gold Rush.
