GROVELAND, CA (August 26, 2013) -- The Rim Fire has grown to 160,980 acres with 20 percent containment according to official at CalFire. Crews made some progress Sunday night fighting the wildfire burning near Yosemite National Park, which has grown to become one of the largest in the state's history.
The fire to threaten several towns, San Francisco's water supply, and historic giant sequoias.
Crews managed to increase containment from 7 percent to 15 percent overnight Sunday, but with the heat of the day only managed to increase containment by an additional 5%. Even with containment, the fire did continue to grow, however, and is now 234 square miles in size.
Stanislaus National Forest spokesman Jerry Snyder said crews are being helped by the fire's movement into less forested areas and cooler temperatures caused at least in part by the shadow cast by the large plume of smoke from the blaze.
About 4,500 structures and Hetch Hetchy Reservoir, the source of San Francisco's famously pure drinking water, remain under threat.
