Crews battling the Arizona wildfire near Sedona have finished creating a perimeter around the fire, but there was no indication Tuesday of when a mandatory evacuation order for the area might be lifted, reports USA Today.
The Slide Fire, first reported at about 4 p.m. on May 20, is burning in Oak Creek Canyon just north of Slide Rock State Park.
Officials believe the fire was human-caused, and the case remains under investigation.
As of Tuesday, the fire had burned 20,328 acres, or nearly 32 square miles, and was 35% contained, said Matt Smyers, a public-information officer for the fire crews.
More than 300 structures, including private home, resort cabins and a Forest Service lookout tower, remained threatened by the fire, according to fire administrators, though that threat had substantially diminished.
Crews have been able to keep the fire from damaging any structures in the area.
