Yosemite fire: The fire covers almost 200 square miles and is only five percent contained. About 17 square miles of the wildfire are now within the Yosemite National Park, but the park remains open to visitors.
After burning for nearly a week on the edges of California's Yosemite National Park, a massive wildfire of nearly 200 square miles has now crossed into it, and firefighters have barely begun to contain it.
The Yosemite Valley, the part of the park frequented by tourists and known around the world for such iconic sights as the Half Dome and El Capitan rock formations and Yosemite falls, remained open, clear of smoke and free from other signs of the fire that remained about 20 miles away.
But the blaze was reverberating around the region. It brought a governor's declaration of emergency late Friday for San Francisco 150 miles away because of the threat the fire posed to utility transmission to the city, and caused smoke warnings and event cancellations in Nevada as smoke blew over the Sierra Nevada and across state lines.
And the fire had established at least a foothold in Yosemite, with at least 17 of its 196 square miles burning inside the park's broad borders, in a remote area near Lake Eleanor where backpackers seek summer solace.
Park spokeswoman Kari Cobb said that the park had stopped issuing backcountry permits to backpackers and had warned those who already had them to stay out of the area.
She emphasized that the skies over Yosemite Valley were "crystal clear," however.
