The Sapphire Pool in Yellowstone Jigsaw Puzzle
- from our Affiliates
The crystal blue Sapphire Pool reaches into the depths of a volcanic caldera in Yellowstone National Park, Wyoming, USA. This amazing phenomenon is created by thermophilic cyanobacteria living in extreme heat originating from one of the world’s largest volcanic calderas. It is truly a natural wonder to behold. These hot springs and geysers throughout the park provide warmth and comfort to hundreds of resident wildlife during the harsh winters inside the park. And in the late spring and summer months these colorful vistas are adored by millions of tourists each year.
