Amazing Morning Glory Pool

Holy Moly, I think I just broke a rib from breathing in too quickly. Look at this amazing Morning Glory pool!!!!

How beautiful is it? The only not beautiful part is that the colours are actually a result of bacteria. But let’s ignore that as we virtually circle ourselves around this wonderful product of nature.


The Morning Glory pool is situated in the Upper Geyser Basin of Yellowstone National Park in the United States. It was named after the Morning Glory flower in 1883 due to its similar sapphire-colour with the flower.

However, over the years, tourists actually threw things into the pool (!!!) and blocked up the vents, lowering the temperature from 200 degrees Fahrenheit (100 Celsius) at the surface to a colder 140-120 degrees (65-50 Celsius), thus allowing cold bacteria to grow. These “cold bacteria” come in a range of different colours, giving the pool it’s rainbow appearance now. 
Cyanobacteria (163 F or 73 C) yellow
Fungi and Algae (140 F or 60 C) yellow/green
Protozoa (133 F 66 C) Orange
Mosses (122 F or 50 C) Brown

I really wish I could have seen the pool when it was still a gorgeous sapphire. If I ever go to the US again, I am definitely adding this to my list, right after Disney World and swimming with the dolphins in Hawaii.
