State fire spokesman Daniel Berlant says crews made good progress against the Rim Fire overnight, increasing containment from 70 to 75 percent. The fire one of the largest in California history also did not grow significantly, with higher humidity moderating fire behavior.
The blaze has now burned about 369 square miles.
The fire began on Aug. 17 in the Stanislaus National Forest, and two-thirds of the land burned since then is located there as well. The cause is being investigated.
It has claimed 111 structures, 11 of them homes.
