Over the past 48 hours, the fire has impacted all of the roads used to access Yosemite Valley, burning dead and downed trees that can become very explosive and fall without warning. Significant terrain hazards for firefighters, along with extreme fire behavior and frequent weather changes, have made it an extremely difficult fire fight.

The following areas remain closed:

Yosemite Valley, El Portal Road, Wawona Road, Big Oak Flat Road, Glacier Point, the Mariposa Grove of Giant Sequoias, the Merced Grove of Giant Sequoias, Wawona Campground, Crane Flat Campground, Tamarack Campground, and several other sections of the Park.
