If you were to guess, not knowing about impact cratering, you might assume that the meteorite was enormous! Actually, the speed and force was so great that a meteor only about 30-50 meters in diameter caused this one mile wide crater. And the landscape was quite different 50,000 years ago, when pinyon forests were filled with megafauna. More about the impact is covered by the Lunar and Planetary Institute
