A lightning-caused wildfire in Grand Canyon National Park has expanded onto the Havasupai Reservation.
Gusty winds caused the Thumb Fire to grow Monday to more than 6,700 acres. Firefighters are building containment lines in remote and rugged terrain north of Supai and helicopters are providing water drops. Crews are also working to protect sensitive natural and cultural resources.
In addition, the Arizona Central West Zone Type 3 Incident Management Team is now in charge of suppression efforts. Smoke is visible from the North and South rims and smoke and haze could fill the canyon. No park closures are in effect related to the fire.
