Clumps of yellow wildflowers and blue grasses cover a foreground of pink sand dunes that frames the mountains and cliffs in the background at Coral Pink Sand Dunes State Park near Kanab, Utah. Afternoon light casts deep shadows in the dips and furrows of the sand dunes. The sand is eroded from Navajo sandstone from the Middle Jurassic geologic period, and its hue is derived from the same iron oxides that color its parent rock.
The sand dunes are created by winds funneled through a notch between the Moquith and Moccasin Mountains that increases its velocity to the point that it can carry the grains eroding from the surrounding sandstone. This is known as the Venturi Effect. The wind’s velocity drops after passing through the notch, and it then deposits the sand, creating dunes in the valley.
The park is host to a variety of flora and fauna, included the Coral Pink tiger beetle, a species exclusive to the dunes.
