Arizona's Yarnell Hill fire — which scorched thousands of acres and killed 19 firefighters — has been 100% contained, fire officials said Wednesday night.

In recent days, as firefighters neared full containment, hundreds of Yarnell residents who evacuated their homes as the flames approached were allowed back into the town. All evacuation orders and highway closures have been lifted, authorities said. 

Yarnell residents were kept out for about a week until they returned Monday.

The fire was started by a lightning strike June 28. It burned through 8,400 acres and destroyed more than 100 structures, authorities said.

On June 30, 19 firefighters — members of the elite Prescott, Ariz.-based Granite Mountain Hotshots — were killed when the blaze overran their position near Yarnell.

The firefighters were saluted during a Tuesday memorial service attended by thousands of locals, firefighters from around the country and political leaders, including Vice President Joe Biden and Arizona Gov. Jan Brewer.

Individual funerals began Wednesday, and some firefighters' remains were returned to their families in California.
