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.[1] 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 good time for photographing The Wave is the few hours around midday when there are no shadows in the center, although early morning and late afternoon shadows can also make for dramatic photos. After a recent rain storm, numerous pools form which can contain hundreds of tadpoles and fairy shrimp. These pools can be present for several days.
