The Grand Prismatic Spring (Yellowstone NP, Wyoming) is huge and although you can walk on the boardwalks along one side of it, it's very difficult to appreciate its size. Before our recent visit to Yellowstone National Park I researched on the internet if there was any way to photograph it from a height. I discovered that if you hiked along a path towards Fairy Falls until you are more or less opposite the spring then walk/climb up the side of the hill, clambering over numerous fallen trees, there is a location where this shot could be taken from. So sure enough we found the path, got to be opposite the spring then looked to our left and the hike/climb up the hillside looked precarious but we tackled it and lo and behold we found a clearing where I took this shot from. A bit of a climb but it was worth it! I could clone out the tops of those three trees but I decided to lave them in. To get above those trees would mean even more of a climb! The colours have NOT been saturated and I didn't use a polarizing filter, the colours are natural.

The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world and it's located in the Midway Geyser Basin, not far from Old Faithfull. It measures about 370 feet in diameter and is over 121 feet deep. The temperature is 147-188°F

Its colours match the rainbow dispersion of white light by an optical prism: red, orange, yellow, green, and blue. The colours begin with a deep blue centre followed by pale blue. Green algae forms beyond the shallow edge. Outside the scalloped rim a band of yellow fades into orange. Red then marks the outer border. Steam often shrouds the spring which reflects the brilliant colours. Grand Prismatic discharges an estimated 560 gallons per minute.
