Fifty houses have been destroyed by a wildfire in California's Gold Rush country and residents under evacuation orders worry their homes may be next.

After days of explosive expansion, the wildfire has slowed down and state fire officials say Thursday's surge in homes burned comes from new discoveries by firefighters and not new destruction.

The Detwiler wildfire remains only 10 percent contained but higher humidity has slowed its growth. The flames have charred 110 square miles (285 sq. kilometers).

The Gold-Rush town of Mariposa being threatened by the fire is essentially empty. Usually at this time of year it would be thronged with visitors on their way to nearby Yosemite National Park.

Now all its residents are under evacuation orders.

Officials say 11 homes have been damaged and 1,500 houses remain at risk.
