Oak Fire Continues To Blaze In Yosemite National Park

Nearly 40,000 firefighters are battling the Oak Fire in California, but the root cause of the fire can't be stopped by just water and fire retardant.

Fire officials are calling it a mega-fire: The Oak Fire is raging through the drought-stricken, forest-covered mountains surrounding Yosemite National Park.

"The fire behavior we are seeing on this incident is really unprecedented," Said Jon Heggie, Battalion Chief of Cal Fire. 

The blaze exploded in size in just a few days, with fire crews driving through the forest with flames surrounding them engulfing the trees and filling the air with smoke. The sky was turned orange, and the fire turned the picturesque forest into a hellscape.
