A Drive through Coral Pink Sand Dunes State Park, Utah, US
Coral Pink Sand Dunes State Park is a state park in southwestern Utah, United States, located between Mount Carmel Junction and Kanab, south and west of U.S. Highway 89 in Kane County. The park features uniquely pink-hued sand dunes located beside red sandstone cliffs.
Venture onto a shifting sea of red sand. Changed by winds, these mountains and hills of sand can move as much as 50 feet per year. With areas for off-highway vehicle enthusiasts and those with non-motorized pursuits, the dunes offer adventures for all.
The geology of the sand dunes is an intriguing subject. The sand comes from Navajo sandstone from the geologic period call Middle Jurassic. The same iron oxides and minerals that give us spectacular red rock country are responsible for this landscape of coral pink sand.
Sand dunes are created by three factors: Sand, high winds, and a unique influence upon the wind. The notch between the Moquith and Moccasin mountains causes this unique influence. The wind is funneled through the notch, thereby increasing wind velocity to a point where it can carry sand grains from the eroding Navajo sandstone.
This phenomenon is known as the Venturi effect. Once the wind passes through the notch and into the open valley, the wind velocity decreases, causing the sand to be deposited. These dunes are estimated at 10,000 to 15,000 years old.
