United States Meteorite Impact Craters

The famous 'Meteor Crater' of Arizona.  The Barringer Crater is a 1.2 kilometer simple, bowl shaped crater formed about 50,000 years ago by an iron impactor about 30 meters across.  The crater is extremely well preserved, and is open to the public for viewing.  An interpretive center is located at the crater rim, and camping and RV facilities are available.  Short tours along the crater rim provide background and present an opportunity for questions and photographs. 

Many fragments of iron-nickle meteorite associated with the impact have been found at this crater.  No collecting is allowed in or around the crater, though many examples of the meteorite, a large number of which were gathered in the first half of the 20th century, are available int he marketplace.  The last time I visited, samples of both the meteorite and its weathered remnants were available for purchase in the gift shop, along with a variety of other intersting items, including mm scale impactite spherules found around the crater.

Evidence of Impact Origin

An impact origin for each location listed on this website has been supported by unambiguous diagnostic evidence of hypervelocity impact that has been reported in a scientific (usually peer reviewed) context.  Without such evidence, a geological structure is not a confirmed impact crater.  This section, which is included for each crater on this website, is not an exhaustive list of such published evidence, but is meant to demonstrate that appropriate work has been done.

A Visit to the Barringer Impact Crater:

Barringer Crater, also known as Meteor Crater, Arizona, or Canyon Diablo Crater, is one of the world's youngest, most extensively studied, and best preserved meteorite impact craters.  The location has been extensively developed as an educational and interpretive facility. Buildings, parking, and trails have been put in place both to protect the crater and to maximize the visitor's opportunity to view and learn about the structure.

Barringer Crater is located at the end of a clearly marked paved road, a few miles south of Interstate 40, between Winslow and Flagstaff, Arizona.  Meteor Crater Road is accessed from exit 233. The location is clearly identified on both highway and private signs.

Though there is little else in the immediate area, Flagstaff and Winslow are both within an hour's drive, and a fuel station and RV campsites are available near the entrance to Meteor Crater Road, just a few miles from the crater.  There is also a restaurant at the crater museum and interpretive facility.

Driving south from Interstate 40, on Meteor Crater Road, the raised rim and proximal ejecta blanket of the crater becomes visible from several miles away, and it dominates the horizon as you approach the interpretive center on the crater rim.  

Barringer Crater is a National Natural Landmark.  It is about 1.2 km in diameter, and is about 170 meters deep.  It is only about 50,000 years old, and is extraordinarily well preserved.  Most of the crater rim is still present and well defined.

The impact crater is privately owned by the Barringer family, through the Barringer Crater Company.  The family has done a great deal to support research in the field of astrogeology and impact crater research science.  A visitor center, combining interactive educational exhibits, crater history, gift shop, and crater viewing and guided tour opportunities, has been built into the crater rim.  The visitor center is open daily, during all seasons.  The official crater website with further visitor information can be found at .

While hunting meteorites in the area is strictly forbidden,the Barringer Crater visitor center contains a gift shop at which visitors can scratch a collecting itch by purchasing small, heavily oxidized examples of the associated iron meteorite at surprisingly reasonable prices, as well as other geological and decorative oddities.

For scientists, students, and serious collectors, the gift shop also makes available very reasonably priced samples of the Coconino Sandstone 'rock flour', in which the high pressure mineral polymorph of quartz, coesite, was first discovered in an impact crater environment, as well as samples of the ejecta-bearing sand from outside the crater rim, in which countless small iron spherules are found.  Research has shown that these spherules account for the bulk of the impacting meteorite.  The iron condensed from vapor in the post-impact plume, and rained out of the sky down range from the impact.

Barringer Crater was formed by the impact of a small asteroid, the remnants of which are referred to as the Canyon Diablo meteorite.  Canyon Diablo is a type IAB-MG iron nickel meteorite.  The largest fragment of the impactor found to date is the Holsinger meteorite, which weighs about 639 kg, or over 1400 lbs. It is on display in the Visitor Center museum area.

The Meteor Crater Visitor Center museum offers a wide range of interpretive and educational displays relating to the history of the crater, spaces science, and impact related astrogeology.  Many of the exhibits are interactive.  Dioramas allow visitors to take pictures as if they were standing on the moon-like floor of the crater or with an astronaut.  Consoles encourage people to simulate asteroid impact parameters such as velocity, impactor mass, and impact angle, and then view the resulting crater formation.  And displays of samples of impact related rock formations, cross sectional maps of the crater, and introductions to the faces and names of the scientists and explorers who have worked at the site engage visitors in a real understanding of Meteor Crater's contribution to our understanding of our place in solar system history.

A paved and wheel chair accessible trail, starting at the visitor's center, provides remarkable viewing along the top of the crater rim.  To say that the view is astounding doesn't capture the experience.  The astoundingly well-preserved crater appears as if it could have been blasted out of the ground within recent decades.  It is deeper than the height of the statue of liberty, and the downtown area of San Francisco could sit in the crater floor.  The rim is nearly always windy, since the compressed and overturned rock still rises nearly 200 feet, or 61 meters, above the flat, surrounding plain.  The huge, deep blue desert sky of Arizona looks as if you could reach out and touch it, and one becomes acutely aware of how vast the emptiness of space is beyond that blue veil, and of what adventures, dangers, and opportunities await us there.

Barringer crater is about 1.2 km, or about 3/4 of a mile, in diameter, and about 170 meters, or about 560 feet, in depth.  The average height of the rim is about 45 meters, or a little under 150 feet.  It was formed by the impact of an asteroid measuring somewhere around 50 meters, or about 160 feet, in diameter, which was traveling somewhere between about 28,000 and 45,000 miles per hour, or about 28 to 45 times as fast as the fastest bullets ever fired from a conventional rifle.

Guided tours of the crater, starting at the interpretive Visitor's Center, are provided at regular intervals.  The crater's website offers larger group tours by arrangement.  The tours are delivered by knowledgable personnel, and are solidly based in a current best understanding of impact science.  They provide a substantive introduction to the history of the crater and its exploration, to the basics of impact science, and to some of the impact-produced geological phenomena visible in and around the astrobleme.  The structure shown in the picture above was used to store dynamite during early attempts at mining the crater for iron.

Explosive excavation during a large meteorite impact event pushes soil and rock at the crater rim upward and outward, away from the point of impact.  Rock layers at the top of the crater rim can be vertical or completely overturned, as shown above.  Barringer is one of the first studied and best studied impact craters in the world.  Many of the classic features of large meteorite impact craters are clearly visible here, and quite a few of them were initially described and named from this locality, before they were observed elsewhere.

The visitor's center and viewing areas provide an unhurried atmosphere for contemplation, photography, or discussion, and the views of the crater are as impressive as they are unique.

The nearly vertical beds of Moenkopi sandstone shown in the picture above were originally the uppermost layer of sediment, at the time of the impact.  In the post-impact crater rim, this layer is folded back upon itself, and is overlain by Kaibab, Toroweap, and Coconino rock units that were originally underneath it.  Looking out across the crater, the layers can be seen in order, and then repeated in reverse order where they overlie themselves in the raised and overturned rim.

A side note on the way to the crater: In the distance, to the east, on the south side of the interstate, near the entrance to Meteor Crater Road, you can see the ruined remnants of Harvey Nininger's American Meteorite Museum.  Though his museum is only a memory now, Nininger's research and educational work contributed substantially to the emergence of the modern disciplines of meteoritics and impact science.
