Midway Geyser Basin In Yellowstone National Park, Wyoming 2010

Midway Geyser Basin: Exelsior Geyser Crater – Grand Prismatic Spring

The next stop was Midway Geyser Basin at the Firehole River. The Midway Geyser Basin is very famous for being the home of the Grand Prismatic Spring. The Grand Prismatic Spring is famous for its size and colors. With being deeper than a 10-story building and larger than a football field, it is the thrid largest hot spring in the world. The Grand Prismatic Spring gets its rainbow colors from the bacteria that lives in progressively cooler water. And the water scatters the blue wavelenght of light, and therefore the center reflects blue back to our eyes.

The Excelsior Geyser Crater is a dormant geyser, but a steamy blue spring. It is so hot, that the runoff water is still boiling, when it hits the surface of the Firehole River. The last time the geyser erupted about 80 feet (25 meters) high for two days was in 1985. Back in the 1800s it could reach a height up to 300 feet (90 meters).

When we visited, we also could see wildlife and wildflowers across the river. We’ve seen a big male bison grassing in the meadow, a relaxing female elk, a couple of ravens, and a big Flame Skimmer dragonfly. There were also wild roses and beautiful pine trees in the area. After the Midway Geyser basin visit, Kevin and I called it a day. We all were hungry and tired for walking around. Sara needed a small nap, before we had dinner at the camp ground. That night, we went to bed early to have an early start the following morning.
