Firefighters on Saturday battled to gain control of a fast-moving wildfire raging on the edge of Yosemite National Park that is threatening power and water supplies to San Francisco about 200 miles (322 km) to the west. The fire, which had grown to just over 125,000 acres (50,585 hectares) as of early Saturday, remained largely unchecked with extreme terrain hampering efforts at containment. [Photo/Agencies]
