Grand Prismatic Spring at Yellowstone National Park
Beautiful and deadly
Elevation 7,270 feet (2,220 m)
Temperature 160 °F (70 °C)
Depth 160 feet (50 m)
The vivid colors in the spring are the result of microbial mats around the edges of the mineral-rich water. The mats produce colors ranging from green to red; the amount of color in the microbial mats depends on the ratio of chlorophyll to carotenoids and on the temperature gradient in the runoff.
