A wildfire burning in a Contra Costa County wilderness park led to the evacuation of several dozen homes Sunday.
The California Department of Forestry and Fire Protection says the fire started Sunday afternoon on the edge of Mount Diablo State Park. Several hours later it had grown to 800 acres and spewed a plume of smoke visible for miles around.
About 50 to 75 homes in Clayton, a town of 11,000 people alongside the park, were under evacuation orders late Sunday, when the fire was 10 percent contained.
About 200 firefighters from several surrounding agencies, along with planes and helicopters, were battling the blaze.
Temperatures in the area hovered near 100 degrees Sunday.
Meanwhile, the cost to fight another wildfire burning in the state has exceeded $89 million.
The U.S. Forest Service reported Saturday that the Rim Fire burning in and around Yosemite National Park has chewed up 394 square miles -- including parts of San Franicsco's municipal power and water infrastructure in the area.
It became the third-biggest wildfire in modern California history. The fire started in the Stanislaus National Forest on Aug. 17.
