Two days a year in the enchanting landscapes of Monument Valley a mysterious event occurs. The Mittens, designated as the East and the West are two free-standing sandstone buttes , two classic iconic symbols of Monument Valley. In March and September, the West Mitten's shadow will land on the East Mitten in a perfect reversed image. A photographers dream. When all the elements play well together, the sunset, clouds and a little magic, something truly spectacular occurs.
