At least 100 firefighters are working to extinguish flames that engulfed 15 acres near the Tonto National Forest.
Two Hotshot crews, three engines, two heavy air tankers and three helicopters were sent to contain the fire, Forest public affairs officer Paige Rockett said.
Fire officials were first called about 6 a.m. Monday to one mile east of Pine, where the fire had spread across steep terrain, she said. No homes surrounding the area were in danger. Pine is about 110 miles northeast of Phoenix.
“They are optimistic they’re going to get the fire under control soon,” Rockett said.
The cause is under investigation.
