California's Rim Fire Still Barely Contained

One of California's biggest-ever wildfires continues to burn largely out of control, more than 100 miles west of San Francisco.

The Rim fire is now growing more slowly than it did last week.

It hasn't yet forced Yosemite National Park to close or affected San Francisco's famously pure water supply, which is drawn from the a reservoir in the fire zone.

But the fire did close two of the region's hydroelectric power generating facilities last week, forcing the city to purchase electricity on the open market.
