A couple photographing The Wave
The Wave is a sandstone rock formation located in the Arizona/Utah border on the slopes of the Coyote Buttes, in the Paria Canyon-Vermilion Cliffs Wilderness, on the Colorado Plateau. It is famous among hikers and photographers for its colorful, undulating forms, and the rugged, trackless hike required to reach it.
The Wave is made of Jurassic-age Navajo Sandstone that is approximately 190 million years old. Scientists who study The Wave say that the old sand dunes turned into hard compacted rock over the ages, calcifying in vertical and horizontal layers. Erosion by wind and rain has created the spectacular landscape which appears now. The soft sandstone of The Wave is fragile, one needs to walk carefully to not break the small ridges.
A permit is required to visit The Wave and only 20 permits are issued per day. (Source: Wikipedia_)
