Evacuation orders and advisories have been lifted for several Sierra Nevada communities once threatened by a wildfire in and around Yosemite National Park.
Officials say they still are investigating the cause of the blaze, which started 18 days ago in an isolated area of the Stanislaus National Forest and has burned nearly 370 square miles -- the fourth biggest recorded wildfire in California.
With higher humidity and lower temperatures, the fire reached 75 per cent containment Tuesday, prompting the sheriff's offices in Tuolumne and Mariposa counties to lift evacuation advisories for communities with several thousand structures in the fire's path.
Officials say 111 structures, including 11 homes, were destroyed.
Although no cause has been announced, one local fire chief speculated the blaze might have ignited in an illegal marijuana grow.
