Meteor crater

Meteor crater

Fig. 13.8 . One of the best and earliest known impact craters on Earth, located in the northern Arizona desert. It has been named the "Meteor Crater" for the nearby post office named Meteor, but it is also widely known as the Barringer Crater in honor of Daniel Barringer (1860-1929), a mining engineer and business man, who was the first to suggest, in 1903, that it was produced by meteorite impact. The crater, about 1.2 kilometers in diameter, was excavated about 40,000 years ago during the impact of a nickel-iron meteorite about 50 meters across. When first discovered, about 30 tons of meteoritic iron was found scattered about the crater. The meteorite is officially named the Canyon Diablo Meteorite, after the nearby ghost town of Diablo Canyon. (Courtesy of NASA.)
