Meteor Crater National Park was created from a meteor that struck the American Continent about fifty thousand years ago.
I was fascinated to find out that it was estimated that the meteor had traveled to earth at a speed of approximately 40,000 miles per hour. I was able to touch a fragment of the meteor, that caused the mile wide crater, inside the visitors center.
Neil Armstrong, and other astronauts have trained at the crater site for their moon missions, because the land structure of the area is akin to those of the craters of the moon.
Outside of the visitors center, there is an Astronaut Hall of Fame dedicated the all of the astronauts who at trained at the crater site.
