West and East Mittens - Monument Valley Navajo Tribal Park, UT and AZ. Stormy skies provide a dramatic backdrop for the towering rock formations of Monument Valley. Visitors are often surprised to learn that the area is not a national park. It is a tribal park, administered by the Navajo Indian Nation, where Indians still live, herding sheep and goats, weaving rugs, and living in mud and log structures called hogans.Photo: Russ Finley Film Size 6X7cm
