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. Helicopters will provide water drops to support firefighters on the ground to slow the growth of the fire. Additional firefighting resources are on order to assist in the wildfire suppression effort.
