After the 1990 Census, the district was reconfigured to include the Hopi Reservation on the other side of the state. This was a product of longstanding disputes between the Hopi and Navajo. Since tribal boundary disputes are a federal matter, it was long believed inappropriate to include both tribes' reservations in the same congressional district. However, the Hopi reservation is completely surrounded by the Navajo reservation. The final map saw the Hopi reservation connected to the rest of the district by a long, narrow tendril stretching through Coconino County. This was the only way to allow the district to remain contiguous without covering significant portions of Navajo land.
