It turned out that under the western United States there was a huge cauldron of magma, a colossal volcanic hot spot, which erupted cataclysmically every 600,000 years or so. The last such eruption was just over 600,000 years ago. The hot spot is still there. These days we call it Yellowstone National Park. We
In the western United States, there exists a massive reservoir of magma that forms a significant volcanic hot spot. This geological feature has experienced major eruptions roughly every 600,000 years, with the last significant eruption occurring just over 600,000 years ago.
Today, this active hot spot is recognized as Yellowstone National Park. Bill Bryson, in his book "A Short History of Nearly Everything," highlights the fascinating geology of the region and emphasizes the potential for future volcanic activity in this unique area.
