Monument Valley Navajo Tribal Park is at the border of Utah and Arizona. Its entrance is along US-163, 20 miles east of Kayenta, Arizona. The park entrance is still in Utah, but the major part of the park is in Arizona. All tose lands, including Kayenta, belong to Navajo Nation. Paying a modest fee, visitors are allowed to drive on designated sandy and bumpy dirt roads to view various high light points. However, to visit interesting points like Big Hogan, Moccasin Arch, Ear of the Wind and Sun's Eye, one needs to join an Indian guided 4-wheel tour to get into private Indian land. We stayed at Kayenta the night before and arranged a tour that starts from the motel. Without such prior arrangement, one can just drive to the visitor center of the park, and there will be many Indian guides with 4-wheels waiting to be hired. Another longer tour is called "Hidden Valley tour". The latter tour is mainly to view the ruins of ancient ANASAZI Indian but not much spectacular scenary. In Navajo language ANASAZI means Ancient Enemy of Navajo. Some say that the modern Hopi Indian is the decendent of ANASAZI, and others say modern Pueblo Indian is the decendant. From the size of the dwellings in those ruins, ANASAZI Indian seems to be very small in size, but modern Hopi and Pueblo Indians are normal size people. So they seem to have grown a lot in time. Navajo Nation uses Utah time, though both the tribal park and Kayenta are in Arizona. Utah time is mountain time and is one hour ahead of Arizona time that is the same as California time. When the Indian guided tour starts at 9 am, it means Navajo time, not Arizona time. At the case of our tour, an Austrarian couple confused with Arizona time and did not come down on time. Only after phone call to their room. they hurriedly came down to join the tour. A careful reservation clerk will always make sure about this time differemce.
