Grand Prismatic Hot Spring

Category: Outdoor Scenes

 

Photo and caption by Allison Haynie

This photo was taken from the visitor's boardwalk at Grand Prismatic Spring in Yellowstone National Park. The hot spring is unique, not only because it is the largest in the United States, but also for its striking color. The colors are formed from massive colonies of bacteria, which contain different pigments and live around the spring according to water temperature. As water drains off of the searing spring, it forms small terraces of dark deposits seen in the foreground of the photo. In the background, evidence of the Yellowstone fires of 1988 are visible in the form of many fallen trees.

Location: Yellowstone National Park, Midway Geyser Basin, Wyoming, United States
