Coming from the outer reaches of the solar system an extraterrestrial body impacted the Colorado Plateau in what is now Northern Arizona about 50,000 years ago during the Pleistocene epoch. The iron meteor created an enormous crater and devastated the surrounding woodlands inhabited by mastodons and other megafauna. Shockwaves traveling through the air and ground effected a large area and enormous amounts of rock and ash were ejected into the atmosphere.
A look over the edge of this crater shows the frightening power of such collisions.
