Ages ago, before humans lived in North America, a space rock pierced the atmosphere and screamed in a blaze of light toward the surface of the Earth. Oh, the catastrophe it must have been when the meteor hit the ground near modern-day Winslow, Ariz. The hole it left behind was a mile wide. Fifty thousand years later, I walked right into it. A view from the trail that leads to the bottom of the crater in Northern Arizona. The meteorite that struck here was about 150-feet in diameter.
