Meteor Crater, or Barringer Crater, is an impact crater about 37 mi (60 km) east of Flagstaff and 18 mi (29 km) west of Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite , after the adjacent Canyon Diablo .
The Middlesboro crater (or astrobleme) is a meteorite crater in Kentucky, United States. [2] It is named after the city of Middlesboro, Kentucky, which today occupies much of the crater. The crater is approximately 3 miles (about 5 km) wide and its age is estimated to be less than 300 million years . The impactor is estimated to have been about ...
The Canyon Diablo meteorite refers to the many fragments of the asteroid that created Meteor Crater (also called Barringer Crater), [3] Arizona, United States.Meteorites have been found around the crater rim, and are named for nearby Canyon Diablo, which lies about three to four miles west of the crater.
An impact crater is a depression in the surface of a solid astronomical body formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, [2] impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain.

The Ries impact crater was a rampart crater, thus far a unique finding on Earth. [11] Rampart craters have almost exclusively been found on Mars. Rampart craters exhibit a fluidized ejecta flow after impact of the meteorite, most simply compared to a bullet fired into mud, with the ejecta resembling a mudflow.
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
Profile view of the crater. Until 1983 there was no evidence of a large impact crater buried beneath the lower part of the Chesapeake Bay and its surrounding peninsulas. The first hint was an 8-inch-thick (20 cm) layer of ejecta found in a drilling core taken off Atlantic City, New Jersey, about 170 miles (274 km) to the north.
In 1891, Gilbert examined the origins of a crater in Arizona, now known as Meteor Crater but then as Coon Butte. For several reasons, and against his intuition, he concluded it was the result of a volcanic steam explosion rather than an impact of a meteorite. Gilbert based his conclusion on the beliefs that the volume of an impact crater ...
