Firefighters are continually making headway in fighting the Rim Fire on the outskirts of Yosemite National Park: On Sunday, they had contained 45 percent of the blaze, which has now charred a total of 224,777 acres of forest.
It also now has the dubious distinction of being California's fourth largest wildfire in state history, according to CAL FIRE. The fire has burned nearly 350 square miles, essentially twice the size of San Jose or nearly 7.5 times the size of San Francisco.
Increasingly confident fire officials said they expect to fully surround the blaze in three weeks, although it will burn for much longer than that.
