Morning Glory Pool, Yellowstone National Park, Wyoming, USA. This geothermal pool is warmed by the volcanic activity beneath it. The bright colours come from minerals deposited around the pool, and from heat-loving (thermophilic) bacteria and algae. Yellowstone National Park, the world's oldest national park, contains thousands of geysers and hot pools.
