The Wave, Arizona



This is a rock formation on the slopes of Coyote Buttes on the Colorado Plateau.  The Wave is known for its various shapes and winding structure.  It is famous among hikers and photographers for its colorful, undulating forms, and the rugged, trackless hike required to reach it.



The rock type of The Wave is Navajo sandstone.  The two major troughs, which comprise this rock formation, are 19 meters wide by 36 meters long and 2 meters wide by 16 meters long.  The Wave exposes large, eolian sets of cross-bedded sandstone composed of rhythmic and cyclic alternating grain flow and windripple laminae. The rhythmic and cyclic alternating laminae represent periodic changes in the prevailing winds during the Jurassic as huge sand dunes migrated across a sandy desert.  Dinosaur tracks and the fossil borrows of desert-dwelling arthropods, such as beetles and other insects, have been found within the Navajo Sandstone within the North Coyote Buttes Wilderness Area.
