Grand Prismatic Spring, Yellowstone National Park, USA in 4K Ultra HD

The Grand Prismatic Spring offers one of the most stunning views in the Yellowstone National Park. It is the largest pool in the park and the third in the world. It is located in the Midway Geyser Basin and its major feature is its amazing coloration, caused by bacteria, living on the edges of the mineral rich water. The pool is about 370 feet/113 m in diameter and is 121 feet/37 m deep. Several smaller springs are located in close proximity.
