Two large wildfires in eastern Arizona continue to grow, but there was progress with one of the blazes in reducing the threat to nearby communities, officials said Tuesday.

The Telegraph Fire has scorched 56,626 acres in and near the southern edge of Tonto National Forest and is 0% contained, according to Incident Commander Dave Bales. He said the cause of the fire is “human,” but is also still under investigation.

The Incident Information Center said the fire is less that 1 mile from the community of Top-of-the-World, which has about 250 people,.

“It is a fast moving and dynamic fire,” the center’s website (InciWeb) says. Growth is attributed to the winds and the brush, such as chaparral, the center said.

Officials ordered an evacuation for residents in the area of Top-of-the-World, the Pinal County Sheriff’s Office said Sunday morning.

“If you choose to ignore this advisement, you must understand emergency services may not be able to assist you further,” the office said on Twitter.

The fire had burned a few miles south of Superior, a town of about 3,000 people.

To the east, the Mescal Fire in the Mescal Mountains has burned 52,887 acres and is 8% contained, according to the Incident Information Center.

“Firefighters made progress today building and reinforcing fireline, despite the continued hot and dry weather,” the center said. “Extreme fire behavior continues to dictate how and where firefighters can safely build line to protect the communities, and powerline.”

Residents in several areas have been told to evacuate, according to the Gila County Health and Emergency Management Facebook page.

Officials think the fire was started by a person but are still investigating the cause.

No deaths or injuries have been reported in either fire.
