While the Rim Fire has consumed at least 12,000 acres in the northwest section of the park, it has had little or no direct impact on Yosemite Valley, a popular spot for tourists and home to many of the famous cliffs and waterfalls in the park.
The park has closed a few roads, campgrounds and wildlife trails while restricting smoking and building camping or cooking fires in wilderness areas.
About 5,500 structures, many of them vacation homes, were under threat, according to InciWeb, a federal website that collects information from agencies such as the U.S. Forest Service and Bureau of Land Management. The fire has cost more than $20 million, Bentley said.
Thirty-one residences and 80 outbuildings have been destroyed.
The inferno threatened the Yosemite gateway communities of Groveland and Pine Mountain Lake just outside the Stanislaus National Forest.
"Business is slow, very slow," said Corinna Loh, owner of the Iron Door Saloon in Groveland.
Her normal season is Memorial Day to Labor Day.
"This is time we manage to save up money to make it through the winter, so it's really scary for all of us," she said, sitting among empty tables.
The Tuolumne County Sheriff's Office, meanwhile, issued evacuation advisories for the town of Tuolumne and nearby Ponderosa Hill, InciWeb said. It was not clear how many residents were covered by the evacuation advisory.
Authorities say the Rim Fire started on August 17. The cause is under investigation.
