History of The Grand Prismatic Spring
The first reports of The Grand Prismatic Spring came from European explorers in the early 19th century.

In 1870, the Washburn-Langford-Doane expedition visited this place and recorded a geyser with a height of 50 ft. This place is also known as Excelsior. A year later, in 1871, the survey team of geologist Ferdinand V. Hayden officially recognized and named this stream after its outstanding color.

The Grand Spring with enchanting colors

In spring, The Grand Prismatic Spring comes alive with a carpet of colors that range from green to red. In the summer, this place puts on a prominent “shirt”, overwhelmed with red and orange colors. While in winter, Grand Prismatic becomes softer with fresh dark green.

So, what exactly gives The Grand Prismatic Spring this mesmerizing color change? The Smithsonian magazine explained that the cause is the microbial mat that exists here. It consists of many layers, mainly bacteria and archaea.

Because water from hot springs can flow continuously without interruption. Thus, they continuously go through a cycle of rising, cooling, descending, rising again. From there, they form rings of different water temperatures, and the central area of the stream is where the temperature is hottest.

Because the water in the center of the spring is so hot, most life cannot exist. Therefore, the central area is always blue. However, different types of bacteria can survive in subsequent rounds of the stream with varying degrees of heat. It is from there that each heat zone can sustain different types of bacteria, giving The Grand Prismatic Spring its mesmerizing color.
