A few frames of the U.S. Postal Service's most remote route. In this desolate part of Arizona near the Grand Canyon, mules haul packages down the winding trail that leads to Supai Village on the Havasupai Reservation. Supai Village, inhabited by members of the Havasupai Tribe, is located eight miles from the nearest road. Accessible only by pack animal, on foot or by helicopter, it is the last place in the U.S. where mail is still delivered by mule. The U.S. Department of Agriculture calls Supai Village the most remote community in the contiguous United States.
