Grand Prismatic Spring
Measuring about 250×380 feet, and being the largest hot water spring outside of New Zealand, the Grand Prismatic Spring is definitely something worth gazing at.
It sits in Yellowstone, high on the top of a mound, and has some small terraces that highlight even better the amazing colours created by the bacteria inside the water.
The vivid colours are the result of pigmented bacteria; the colours range from green to red, depending on the amount of chlorophyll the bacteria has, as well as the temperature of the water.
