A new forest fire was reported north of Cave Creek Saturday. Tonto National Forest officials say the Bronco Fire has burned about 40 acres of land near Seven Springs Road (FR 24) near Sears Kay Ruins. There is zero containment. Three air-tankers, and one air attack plane, with multiple engines are working to contain the spread of the blaze, officials say. Firefighters have been preventing threats to structures and protecting power lines in the area throughout the afternoon. Forest officials say the spread and intensity of the fire has decreased into the evening hours. Crews continue to monitor for potential threats to structures and are building containment lines. They ask that the public avoid the area to allow fire vehicles and crews to safely access the incident. Seven Springs Road (FR 24) is closed at this time. This is just one of numerous fires burning across the state.
