Yellowstone National Park is one of the most visited National Parks in the country. In fact, in 2021, over 4.8 million people visited America’s first National Park. It’s also one of the most dangerous parks to visit if you aren’t paying attention or choose not to follow posted rules and regulations.
The entire park’s hydrothermal system lies above the immense Yellowstone volcano. The molten magma body in this region of the United States is what produces the thermal activity and unique landscape. When it rains, the water seeps through the bedrock and becomes superheated far below the Earth’s surface.
Throughout this vast National Park, there are 10,000 hot springs, geysers, mudpots, and fumaroles dispersed across 3,472 square miles. However, they’re not all accessible and open to the public.
