A deep, funnel-shaped pool with a dark blue center resembles to the corolla and the color of Morning glory, where its name associated. It was given that title in 1883 by the wife of an assistant park superintendent. Just in recent, the pool has started to go by another name "Fading Glory". Temperature: 171.6 degrees F. Dimension: 23x26.6 feet. Depth: 23 feet. It has been a popular thermal feature at Yellowstone.
The delicate blue water is created by thermophilic bacteria, which thrive in the pool's searing heat. Long a ago, in Yellow National Park, The Morning glory suffers from the inconsiderate visitors who have thrown trash in the pool for over a century. This cause the slowly built up and blocked some of the thermal vents and reduced the heat of the pool, allowing the bacteria to begin at the edges, thus this creates the red and yellow ring around the pure blue water. Occasionally, often following seismic activity, the pool erupts in a geyser.
