A destructive wildfire near Yosemite National Park, that has grown into one of California’s biggest blazes of the year, could not be contained on Sunday.

About 2,000 firefighters were battling the Oak Fire, along with aircraft and bulldozers, facing tough conditions that included steep terrain and spiking temperatures, according to the California Department of Forestry and Fire Protection, or Cal Fire.
