Grand Canyon, AZ – The Thumb Fire continues to expand to the south on the Havasupai Reservation pushed by gusty and erratic winds. The fire was mapped late yesterday at 6,726 acres. The Arizona Central West Zone Type 3 Incident Management Team was delegated the management of the fire and is providing interagency support to Grand Canyon National Park, Truxton Canon Agency, and the Havasupai Tribe.

The team will continue suppressing the lightning caused fire while performing actions that protect identified sensitive natural and cultural resources. The Incident Management Team will support firefighters that are working in the remote and rugged terrain north of Supai as they build containment lines and strengthen natural containment features like roads, trails, and rock outcroppings.
