Shown silhouetted at sunrise on this photo, Mitten Buttes in Monument Valley, Arizona, proudly stands over the barren landscape on the Navajo Indian Reservation, north of Kayenta, Arizona. Mitten Buttes consist of soft sandstone and date from approximately 250-300 million years ago (Cutler Formation). These upright monuments contain many vertical joints, which play a major role in their erosion. Mitten Buttes have been the setting for several John "Duke" Wayne "westerns."
