The blaze injured three people, put hundreds under evacuation orders and threatened 460 structures, officials said.

A nearly 40,000-acre wildfire forced people from their homes in two Southern California counties over the weekend as firefighters worked to contain the blaze in challenging terrain.

Fire managers for the U.S. Forest Service put Gifford at 49,761 acres (77 square miles), with 3% containment. Three people were reported injured: a civilian who was burned, and two contractors who were injured in an off-road utility vehicle’s rollover.
