Where A Meterorite Struck The Earth
Approximately 50,000 years ago a huge iron-nickel meteorite 150 feet in diameter and weighing 100,000 tons crashed into the Colorado Plateau of northeastern Arizona. Traveling at 26,000 miles per hour, it struck the plateau with an explosive force greater than 20 million tons of TNT. In less than a few seconds, a crater 700 feet deep and over 4,000 feet across was carved into this once-flat rocky plain.
