The Yellowstone National Park natural wonder can shoot jets of hot water as high as 90 meters into the air. Yellowstone sits on top of a vast crater, and an enormous upwelling of magma from the Earth’s core. “There is nothing to indicate that any sort of volcanic eruption is imminent,” the US Geological Survey’s Yellowstone Volcano Observatory head Michael Poland told Reuters. So, Steamboat’s blast of activity “might just reflect the randomness of geysers,” Poland says. It wasn’t until the 1960s that it was realised the 70km-wide natural basin was an old volcano caldera.
