SUPERIOR, Ariz. (AP) - A wildfire near Superior has charred nearly 2,700 acres but is now 40 percent contained.
The fire began Sunday in the Tonto National Forest northwest of Phoenix and is burning in steep, rugged terrain.
Authorities say the cause of the so-called 257 fire is under investigation. The name comes from Forest Road 257, which is where the fire started in a wash.
Nearly 200 firefighters are battling the flames about 3 miles south of Superior. The fire isn't threatening any structures.
Meanwhile in northern Arizona on the Navajo Nation, a wildfire south of Klagetoh has burned about 600 acres with zero containment.
Bureau of Indian Affairs officials say the wildfire is human caused and under investigation. No structures have been damaged, but eight families have been evacuated as a precaution.
