View from road to Mystery Valley - Monument Valley Navajo Tribal Park, UT and AZ. Mystery Valley is a peaceful canyon where isolated monoliths of red sandstone rise up to 1,000 feet above the valley floor. On Indian-guided horseback tours, visitors can view prehistoric Pueblo (Anasazi) ruins, petroglyphs and natural arches, and even camp under the stars.Photo: Russ FinleyIndian, Anasazi, Ancestral Puebloan, reflection Film Size 6X7cm
