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

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.

The Gifford fire has rapidly spread after firefighters contained the Madre fire. Together, the two blazes have already burned over 100,000 acres.
