FOR YOUR EYES ONLY // 18th February 2013
Yellowstone National Park in Wyoming, USA, gathers half of the world’s geothermal features. Stretching on an area of nearly 9000 square km, the national park is home to 10,000 geysers, hot springs, mud pots, and fumaroles. What one’s calls “Yellowstone” is a massive volcano that erupted with tremendous force several times in the last two million years. Lava flows and rocks from volcanic eruptions cover most of the land area of the park which is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining, nearly intact ecosystem in the Earth’s northern temperate zone.
There are several hot springs to be seen there, such as the Grand Prismatic Spring, the largest in the Yellowstone National Park and in the United States, and the third largest in the world. It is located in the Midway Geyser Basin.
The Grand Prismatic Spring was discovered in 1871 by geologists and named by them for its striking coloration. Its colors – blue, green, yellow, orange, gold, red and brown – gave name to it, as they recall the rainbow of an optical prism.
The Crested Pool is another wonder to please the eyes. It is a 42 feet deep hot spring in the Upper Geyser Basin in Yellowstone National Park that erupts from time to time, like a geyser.
Chromatic Spring is located in the Upper Geyser Basin of Yellowstone National Park and has connections to the nearby Beauty Pool.
Emerald Spring is located in Norris Geyser Basin of Yellowstone National Park and gets its name from the emerald green color of the water.
Lion Geyser is a cone-type geyser in the Upper Geyser Basin of Yellowstone National Park that was named for the roaring sound it makes when steam releases during an eruption. Eruptions can reach 90 feet and last from 1 to 7 minutes.
Morning Glory Pool is located in the Upper Geyser Basin of Yellowstone National Park. The pool was named by the wife of an Assistant Park Superintendent, in 1883, after she called it “Convolutus”, the Latin name for the morning glory flower, which the spring resembles.
