Porcelain Basin (1991)

A wide view of Porcelain Basin, a section of the Norris Geyser Basin in Yellowstone National Park. The collection of geysers and pools offers some of the hottest water in the park, as well as a landscape that looks like a matte painted background for a science fiction movie. The bright orange color comes from thermophilic microbes that thrive in the boiling sulfurous water. The milky white calcium deposits from a hot spring in the background give the basin its name.
