LOS ANGELES — Firefighters hoped to continue making progress today on the Rim Fire near Yosemite National Park, which has already burned through more than 160,000 acres but was 20 percent contained.
The fire was threatening 4,500 homes Monday night.
A persistent air attack Monday helped firefighters make progress in their battle to stop the westward spread of the massive fire.
The blaze that broke out Aug. 17 was still spreading to the north and northeast into old growth timber in the Stanislaus National Forest.
The flames have also raged into Yosemite, burning nearly 22,000 acres of parkland, officials said.
