A wildfire sparked in Yosemite National Park on Sept. 7 grew to an estimated 455 acres Friday, and was 25% contained.
Dubbed the Tenaya Fire, the blaze continues to flank across slopes, creep through surface fuels, and the understory of trees.
Some single tree torching was also noted. One minor injury has been reported, with no threats to structures in the area.
Firefighting effors at the heel, or anchor point, continue to hold as they reportedly make good progress along both flanks of the fire, located along the Lehamite Creek Trail from the north rim of the Valley to the Tioga Road.
Firefighters are looking for opportunities to tie fire lines into granite rock, trails, and other natural barriers with the least impacts to the park.
Assisting organizations fighting the blaze include the U.S. Forest Service, Bureau of Land Management, and other National Park Service resources. There are 241 personnel at work on the inferno.
Risks could spread to the Tioga Road, but there have been no road closures thus far. All trails on the north rim of Yosemite Valley, south of the Tioga Road, and east of Yosemite Creek are closed. Trail blocks are in place.
