Death Valley, NP
Artist Drive rises up to the top of an alluvial fan fed by a deep canyon cut into the Black Mountains. Artist Palette is an area on the face of the Black Mountains noted for a variety of rock colors. These colors are caused by the oxidation of different metals (iron compounds produce red, pink and yellow, decomposition of tuff-derived mica produces green, and manganese produces purple).
