Imaggeo on Mondays: Salted Moon

The eerie landscape depicted in our Imaggeo on Mondays image, is brought to you by Donatella Spano (University of Sassari, Italy).

This picture was taken at Mammoth Hot Springs, one of the largest hot spring areas at Yellowstone National Park, Wyoming, United States on August 10, 2010. Mammoth Hot Springs is divided into two sections, the Lower Terrace and the Upper Terrace Loops. The photo below shows the Upper Terrace. A combination of heat, water, limestone, and rock fractures created the terraces of the area. The main deposit is travertine, a form of limestone derived by mineral springs, especially hot springs. It is formed by a process of rapid precipitation of calcium carbonate. Travertine is often a white rock; however, the microorganisms and living bacteria create beautiful shades of oranges, pinks, yellows, greens, and browns. The constant changes in water and mineral deposits create a living sculpture. This massive hot spring is extremely photogenic. The day I took the photo there were dark clouds creating interesting contrast between the surface, the mountain, and the sky.
