| Morning Glory Pool |
The Original name of the Morning Glory Pool was Convolutus. It was given that title in 1883 by the wife of an Assistant Park Superintendent, after the Latin word for the morning glory flower, which the pool's blue color resembles. Recently, however, the pool has started to go by another name "Fading Glory."
The delicate blue water is created by Thermophilic Bacteria, which thrive in the Pool's Searing heat. Long a major tourist stop in Yellowstone National Park, the Morning Glory Pool suffers from inconsiderate visitors who have thrown coins, bottles, and trash into the pool for over a century. The trash has slowly built up and blocked some of the thermal vents and reduced the heat of the pool, allowing other bacteria to begin working their way in at the edges, creating a red and yellow ring around the pure blue center. While this rainbow hue is indeed beautiful, it is a fragile beauty, as the invasive yellow bacteria continues to close in.
Occasionally, often following seismic activity, the pool erupts in a geyser. There is hope that these eruptions may clear the pool of trash. Attempts have been made to artificially induce geysers, but have met with mixed results.

How 'good luck' coins thrown into a hot spring have turned one of nature's wonders into a lurid hue of green
For Decades it has proved a Popular Tourist Attraction.
And while the Morning Glory Pool in Wyoming with its stunning colours continues to attract visitors from around the world its appearance has undergone a dramatic change.
Just a few decades ago, the natural hot spring was a distinctive blue colour.
But now it has taken on a deep green hue with a distinct yellow and red ring around its circumference.

Tourists have for decades been throwing coins into
the Morning Glory Pool in Wyoming for luck.
These have blocked its heat vents thereby reducing its
temperature and causing a chemical reaction

before the chemical reaction took place
While still an extraordinary spectacle, the reason for this change is less alluring. Tourists have for decades been throwing coins into the pool for luck. Unfortunately, these have blocked the pool's heat vents and reduced its temperature. At the same time, chemicals from the coins have caused a reaction that has caused several bacteria to grow. These have slowly worked its way to the water's edge, creating the predominantly yellow ring around the pure blue centre which has turned green as a result. The algae is photosynthetic, thermophilic bacteria that can survive temperatures ranging from 64C to 107C.

IT consultant Arun Yenumula, 30, took the top photograph of the Morning Glory Pool in Yellowstone National Park while on holiday with his wife.
He said : 'I had heard about the pool from friends and when I saw it I thought it was simply unbelievable.
'Each colour represents a different type of heat-seeking algae.
'An information board next to the pool called it "fading glory" because people threw rocks, stones, bottles and cans blocking the heat vents at the bottom, resulting in cooling the pool.
'The bacteria which thrive in real hot water started to die and the colours were fading. I felt really sad about the fact and how humans are destroying nature's beauty with their mindless acts.'
Mr Yenumula, from Seattle, Washington, added: 'Morning Glory is the most beautiful pool at Yellowstone National Park.
'It is unique and has a more diverse range of colours than anywhere else.
Reaction : The algae is photosynthetic,
thermophilic bacteria that can survive temperatures from 64C to 107C
Big draw : The pool attracts thousands of tourists from around the world every year
