Yellowstone Geological Activity Insights

Yellowstone National Park is a geological marvel, home to one of the largest volcanic craters on Earth. Discovered in the 1960s by Robert Christensen, the crater's existence was confirmed through NASA imagery. The park's history is marked by a super eruption 640,000 years ago, evidenced by ash layers found across the Western US. Geologists have recreated the eruption's impact, revealing its massive scale and velocity. Recent studies have unveiled a hotspot beneath Yellowstone, raising questions about future eruptions.
