Pallette Spring, Mammoth Hot Springs, Yellowstone National Park, Wyoming, USA
Near Liberty Cap at the beginning of the boardwalks is Palette Spring.
Water flows from a flat area and then down a steep ridge, creating a colorful hillside palette of brown, green, and orange (the colors are due to the presence of different heat-tolerant bacteria). This effect is much the same as an artist would achieve by allowing wet paint to run down a vertical surface.
Thermophiles, hot water loving bacteria, color the area mostly in oranges and browns.
