Colors Of The Wind
As I stood in awe at the natural colors at Artists Palette in Death Valley National Park, California, my mind wandered to one of the songs from the Disney movie Pocahontas - Colors of the Wind. The “color” of the wind would be the color of whatever gas it's composed of, or in the case of Artists Palette, the color is from the materials (metals, minerals, chemicals, etc…) that exist in the earth.
Artist's Drive rises up to the top of an alluvial fan fed by a deep canyon cut into the Black Mountains. Artist's Palette is on the face of the Black Mountains and is noted for having various colors of rock. These colors are caused by the oxidation of different metals (red, pink and yellow is from iron salts, green is from decomposing tuff-derived mica, and manganese produces the purple). Called the Artist Drive Formation, the rock unit provides evidence for one of the Death Valley area's most violently explosive volcanic periods. The Miocene-aged formation is made up of cemented gravel, playa deposits, and much volcanic debris, perhaps 5,000 feet thick. Chemical weathering and hydrothermal alteration are also responsible for the variety of colors displayed in the Artist Drive Formation and nearby exposures of the Furnace Creek Formation.
