You've probably seen beautiful photos of the sensuously sculpted frozen sand hills. These formations called "The Waves" "The Sands of Time" or North Coyote Buttes. It is actually located in the Paria Canyon-Vermillion Cliffs Wilderness area, Utah-Arizona border. The number of people allowed into the area is strictly limited. Details on how to apply for the permit are given at
Paria Canyon-Coyote Buttes

If you are just photographers, not experienced hikers, I do not recommend you to solo hiking in this area, especially hiking at late evening or dark night. You should be accompanied in a group with an experienced leader.

If you ever want to go hiking or take photograph in this area first time and need information, please feel free to ask, I am more than happy to help you all.
