National Parks
Yellowstone National Park • Some 640,000 years ago, a massive volcanic eruption spewed forth an immense
volume of ash that covered what is now all of the western US, including much of
the midwest, northern Mexico and some areas of the eastern Pacific region. The
legacy of that eruption today is a caldera some 30 mile wide and 45 mile long
now known as the Yellowstone National Park. With bubbling mud and roaring
geysers sending plumes of steam into the sky, these geothermal wonders attract
visitors from all around world. There is more information on the official
website by the National Park Service.
