In northern Arizona, the time situation is nearly as confusing as Indiana. Arizona is not on DST, but the Navajo Indian Reservation in northern Arizona is on DST. To make matters worse, the Hopi reservation, which is completely surrounded by the Navajo Reservation does NOT use DST—it is just like the rest of Arizona. Now if you drive from El Paso (through New Mexico and Phoenix) up past the Grand Canyon and out through the four corners, you’ll have to change your clock four times just getting through AZ. Crazy Native Americans. Silly state.
