Arizona's iconic sight: The Wave

June 25, 2013

Only 20 people are allowed to visit The Wave each day, with 10 chosen in an online lottery

four months in advance and the other 10 picked in a daily lottery. The U.S. Bureau of Land Management limits access to protect The

Wave's delicate red sandstone formation and to prevent overcrowding at

the designated wilderness site in the Vermilion Cliffs National Monument in St. George, Arizona.
