An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Hoba meteorite, Namibia / Damien du Toit, Flickr / CC BY Largest known impact crater: Vredefort impact structure in South Africa, Free ted diameter of this crater: km. The smallest impact craters are not measured – such small "holes" are short-lived. One of smallest recent craters could be the 6 m wide Kunya-Urgench impact crater (Turkmenistan), which was created in.

  The foot deep crater was left by a meteorite over , years ago. More recently, in the ’s, a factory producing soda ash and salt was . A nontechnical account is given of the development of scientific understanding of meteorite craters on earth. The geology of the craters is discussed in context. Among the topics discussed are: curious landforms of the Colorado Plateau; Meteor Crater in Arizona; the geology of explosive impact, cryptovolcanic structures, coesite and shatter cones, the Sudbury geological puzzle, and impact.

The arc is closely circular, with a diameter of miles.

Dem Ministère des Richesses Naturelles, Québec, Canada, sowie Herrn M.S. Murtaugh sei für die großzügige Unterstützung bei den Geländearbeiten im Manicouagan-Krater gedankt.

Die Deutsche Forschungsgemeinschaft hat die Arbeit finanziell unterstützt. The crater is defined by a m deep circular bay in a lake which elsewhere averages only m in depth.

The shape and depth of the bay contrast sharply with other lakes in the area. Local Indian legend has a taboo on fishing in the bay, presumably due to its unusual appearance and depth.

RV PARK. The Meteor Crater RV Park is located just off Interstate 40 exitless than a 1/4 mile to the right. The large parking lot includes a Mobil Gas Station and Country Store for checking in. Set up your lawn chairs, look into the night sky from the Meteor Crater RV Park, and enjoy one of the finest star and sky shows offered in the American Southwest.

The Carswell crater is the largest known impact crater in Saskatchewan and 4th-largest in Canada. A chain of small lakes trending from southwest to northeast has formed along the rim in this location.
