Officials are battling a new wildfire in southern Arizona.
The Mule Ridge Fire started on May 31 and has now burned 8,522 acres. The fire is located about a mile away from Ruby, Arizona. No structures are currently threatened.
Over 200 fire personnel are on the scene and a Type 3 team has assumed command.
One firefighter suffered a burned arm Saturday and was treated at a medical center in Tucson and was released to his crew.
The southeastern portion of the fire is still active and the majority of crews worked to extinguish this portion on Sunday.
Some crews are expected to be released by the end of Sunday to rest, resupply and be ready for another assignment.
Crews have been challenged by heat stress working in triple digit temperatures.
Grass, brush and oak trees are currently on fire.
The U.S. Forest Service says 50 percent of the fire is contained. Officials say the fire is human caused and is still under investigation at the time.
