The geothermal features at Yellowstone include geysers, hot springs, mud pots, fumaroles, solfataras and terraces, all of which are hot from the internal heat of the earth.
Half of the world’s geothermal features are found in Yellowstone National Park, fueled by volcanism.
The Modern Day Explorer reports:
“Lava flows and rocks from volcanic eruptions cover a great majority of Yellowstone National Park, creating one of the most surreal places you’ll ever visit. In some areas, nearly molten rock flows as little as two to five miles below the surface and you may not even know it.”
While this may seem scary, there are designated pathways around the geysers and dangerous areas so that you can witness these phenomenon’s safely.
If you are traveling with children, please make them aware of the dangers of going off path, and put toddlers and babies in a carrier or stroller.
Be forewarned that geysers emit small amounts of hydrogen sulfide gas. Sulfur compounds have an odor many would say smells of rotten eggs, although the ancients dubbed it the “smell of hell,” according to The Bushbuck Wildlife Tours.
The popular cone geyser, Old Faithful, is named such for its timely eruptions, unlike the other geysers in the park. It erupts 106-185 feet in the air and remains one of the most sought after natural wonders.
Looking at some of the hot springs, you will see radiating colors that look like a rainbow fell to the ground. This is caused by bacteria adjusting to the different temperatures and Ph’s throughout the spring.
Fun fact: The center will be bright blue because the scorching 189 degree water doesn’t harbor any bacteria at all.
