People in the community generally are handling the situation pretty well, though many have evacuated, Riley said.
"I understand we are in a tinder box and it is risky," he said. "But it is beautiful."
The Tuolumne County Sheriff's Department, meanwhile, issued evacuation advisories for the town of Tuolumne and nearby Ponderosa Hill, according to InciWeb. It was not clear how many residents were covered by the evacuation advisory.
Residents of Pine Mountain Lake and another area were to be allowed to return home beginning Saturday evening. Fire crews strengthened lines above Pine Mountain Lake, a resort neighborhood.
"Be advised that areas burned by the Rim Fire may still pose hazards," an advisory said. "Fire-weakened trees, burning stump holes and large fire apparatus may be present. Entry into the burned areas is strongly discouraged."
Authorities say the Rim Fire started on August 17. The cause is under investigation.
Gediman, of Yosemite National Park, said the Rim Fire's impact was restricted to the entrance closure at Highway 120 West and a backcountry section used by hikers. Temperatures were a little cooler Saturday than on Friday, he said.
The park typically has 15,000 visitors on a busy summer weekend. August sees an influx of visitors from other countries, a few of whom have called to check on conditions.
Still, there's little indication so far it's keeping many people away.
Ranger programs went on as normal Saturday and campgrounds were full.
"If somebody cancels, there are 10 people that will take their spot," said Gediman.
Yosemite, with hundreds of campground sites and lodging units, had nearly 4 million visitors last year, according to the National Park Service.
