Long Description:
“The high cliffs around you were created after the last volcanic eruption in the Yellowstone region, about 630,000 years ago. The powerful eruption ejected ash as far away as Nebraska and Texas, expelling magma from an underground chamber more than 30 miles in diameter. As the roof of the chamber collapsed, a caldera or crater, was formed spanning nearly half of Yellowstone National Park. In time, massive lava flows, filled the caldera, creating the present landscape including the cliffs before you.”
