Geyser from Yellowstone National Park

Old Faithful Geyser: the first geyser in the park to receive a name

     Old Faithful Geyser is one of the biggest geyser in Yellowstone National Park, but the most fascinating about this geyser is how humans can predict with an accurate precision within 5 minutes. If you think about it, how can we predict when the water will be heated by magma underground is hot enough to erupt the next time. It is famous because of its high frequency within 90 mins. 

     Yellowstone National Park is one of the major geysers field in the world because it is located over the Yellowstone Caldera, the largest supervolcano on the continent. Some people told me that the eruption of this volcano will cover almost the entire North American Continent with dust.

Castle Geyser: a cone-type geyser

      There are plenty geysers covering the whole area of Yellowstone National Park. However, it is almost impossible to see the eruptions of every geyser in the park within a week because each geyser has their own period for the eruption. We can lucky enough to see several of them erupting during our time there. Castle Geyser is one of them that we have to run back from our hotel to actually see the eruption.

     However, the most exciting geyser in my opinion for this trip was Beehive Geyser. We had to wait for just 10-15 mins for the eruption which is really good because the eruption happened only 10-15 hours. The eruption are nearly 200 feet (61 meters) high into the sky. It covered part of the sky once we looked up and some people got wet from the eruption. The eruption is just unbelievable high from a relatively small cone. It just gave me beyond my expectation about geysers even though I had seen several before seeing this one.

    Geyser is a fascinating geophysical effect from underground heat. It is one of the signs of active world underneath our feet. Another unbelievable feature from Yellowstone is a color hot spring, especially Grand Prismatic Spring.
