Yosemite burning, San Francisco power endangered

Christian Science Monitor - 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.
