The region is inclined to flood, and August is the peak of storm season in Arizona, carrying with it higher humidity that can cause thunderstorms, heavy downpours, lightning, and hail.

Remote Reservation

The Havasupai reservation is one of the most remote reservations in the United States, which can only be reached by foot, horseback, or helicopter making rescue efforts difficult.

Damage from the flooding drove the Havasupai Tribal Council to close the land to tourists until further notice while they deal with the destruction.

According to Hannigan, in a statement she made to The Arizona Republic, “There was not what some people might think of dropping lines (from a helicopter) to pull people up. They were in an orderly fashion and ready to get on the aircraft. It was all very well organized by the tribe. They made our lives a lot easier.”

Supply Drops

The Guard were also involved in dropping off supplies which were made up of necessities such as food and water.

Hannigan went on to say, “When we got there, people were cheering. They were very vocal about sharing excitement to probably get home.”

“Arizona is a small and big state, and the entire community is something that we hold dear, and so being ready and willing to support the community as a whole, it’s just something that comes with a Guardsman”
