This picture was taken in 1927, 19 years after a meteor flew over this area at an estimated altitude of 3 to 6 miles. It caused a shock wave that produced thousands of times the energy in the bomb that destroyed Hiroshima. The explosion knocked down an estimated 80 million trees and would have destroyed a large city if it had happened over a city.
Today various scientific instruments scan the skies to see if any meteors are going to hit Earth. Several movies have been made about how this would happen. It has not happened for a long time but it is expect to in the future.
