Photos from Monument Valley, located on the northern Arizona border with southern Utah. A 17 mile drive through the 16 million acre Navajo Monument Valley park will produce stunning scenery by its sheer size and beauty. The red colour comes from iron oxide exposed in weathered siltstone rock. Often used in the settings for Western movies. This place is stunning and no relief from the sun and heat no matter how many times I danced on Rain God Mesa. Loved the place.
