Morning Glory Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park in the United States.
The pool was named by Mrs. E. N. McGowan, wife of Assistant Park Superintendent, Charles McGowan in 1883. She called it Convolutus, the Latin name for the morning glory flower of which the springs resemble. By 1889, the name Morning Glory Pool had become common usage in the park[1]. Many early guidebooks called this feature Morning Glory Spring.
The distinct color of the pool is due to bacteria which inhabit the water. On a few rare occasions the Morning Glory Pool has erupted as a geyser, usually following an earthquake or other nearby seismic activity.
Several entryways have been clogged due to objects being thrown in by tourists, reducing the hot water supply, and in turn altering the overall appearance of the pool. Several attempts by park officials to artificially induce eruptions to clear the pool of debris and clear blocked entryways have been met with mixed results[2]. As a result of the vandalism, Morning Glory is also known as Fading Glory. 
Scuba diving can be done at all different ages.
