18th Annual Smithsonian Magazine Photo Contest Natural World
A Colorful End

A dragonfly meets its demise on one of Yellowstone National Park's geysers and springs. These ubiquitous natural sinkholes can be highly acidic and incredibly hot, thus, more often than not, deadly for all forms of animal life. The spring's green coloration is caused by different temperatures in the pool which are able to host different types of bacteria.
