LATEST: Guests staying at Tenaya Lodge who need to return to the lodge to retrieve their belongings can meet at the Hwy 41 road closure in Wawona to be escorted to the hotel at 10 a.m.
FRESNO, Calif. (KFSN) -- The blaze was aggressive, fast moving, and relentless; racing up countless trees in the Sierra National Forest that are infested with bark beetle.
The fire even threatened Sugar Pine Railroad and forced employees to move the historic attraction's trains to safer ground.
But Tenaya Lodge, which is a few miles up the road, was in danger too. A family from the Netherlands was staying there until the road closure sent them without their belongings to a hotel in Oakhurst for the night.
"No swimming for us today, unless it's in the nude but it's not allowed over here," said Frank Bakker, tourist from the Netherlands.
Those same road closures along Highway 41 between Cedar Valley Road and Summerdale Campground also created problems for Todd Finnigan. He and his family traveled from England to visit Yosemite.
"Frustrating because we've been driving all day."
The Sierra National Forest said the fire is burning in steep terrain with heavy fuel. They also said hot weather and strong winds made it difficult for crews.
Dan Tune, with the Sierra National Forest, said, "Trees have been weakened so they are coming down, so we have to be real careful with our firefighters putting them out there under some of these things."
Now with 920 acres burned, firefighters who are working throughout the night are hoping a shift in winds will allow them to make more progress.
So far the fire is only five-percent contained.
While 100 structures are threatened there is no word on how many are damaged or destroyed.
