Millions of years ago, the north american continent was dragged over the world's largest continental hotspot, a huge column of hot and molten rock rising from the earth's interior that traced a 50-mile wide, 500-mile-long path northeastward across idaho. Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the yellowstone plateau to more than 7,000 feet and pushed the northern rockies to new heights, forming unusually large glaciers to carve the landscape.
Yellowstone is a geological wonderland, and that geology controls the flora and fauna that visitors enjoy today. The geologic conditions are shaped not just by volcanic eruptions, like the famous large explosions and lesser-known lava flows, but also glaciers and lakes.

Yellowstone national park is one of the most geologically dynamic locations on earth. As such, its complete geological history is beyond the scope of this report, so only some of the major events that have helped to shape today’s yellowstone will be discussed.
The landscape of the greater yellowstone ecosystem is the result of various geological processes over the last 150 million years. Here, earth’s crust has been compressed, pulled apart, glaciated, eroded, and subjected to volcanism. All of this geologic activity formed the mountains, canyons, and plateaus that define the natural wonder that is yellowstone national park.
