Meteor Crater

Meteor Crater, also known as Barringer Crater, is the best-preserved impact site on Earth and one of the great free-standing geology lessons in the American West. About 50,000 years ago an iron-nickel meteorite roughly the size of a large house struck the high desert east of Flagstaff, throwing out millions of tons of rock and leaving a bowl close to a mile across and some 550 feet deep. The dry climate has kept the rim crisp, so the crater looks almost as it did when the dust settled. It sits on private land about 40 miles east of Flagstaff, just off Interstate 40, and it is run as a visitor attraction with an interactive discovery center, a museum of meteorite science, guided rim walks when conditions allow and viewing platforms that let you take in the full scale. Many first-time visitors admit that photographs do not prepare them for how big the hole really is.

The science is the hook. Daniel Barringer, a mining engineer, argued in the early 1900s that the crater was an impact scar and spent years drilling for the buried meteorite, a financial gamble that failed because the impactor largely vaporized on arrival. His idea was correct, though, and the crater became the template for understanding impacts across the solar system.

The visitor center explains how shock waves, melted rock and fragments of the Canyon Diablo meteorite prove the story, and a good short film and galleries walk through the physics. Children tend to love the real meteorite you can touch and the scale comparisons that show how a stadium or a skyscraper would fit into the pit.

Space history gives the place extra depth. Apollo astronauts trained here in the 1960s, using the crater as an analog for lunar surfaces, and an outdoor memorial and a test capsule recall that era. Walking along the viewing areas and, on guided tours, a short stretch of the rim, you can see the layered limestone and sandstone that were flipped upside down by the blast.

Wind can be strong and sudden at the rim, and weather occasionally limits access to the outer trails, so check conditions on the day. The rim itself is high desert at about 5,700 feet, with little shade, so summers are hot and winters can bring snow and icy paths.

Practical planning is easy. Allow roughly two hours on site, plus about 45 minutes each way from Flagstaff on the interstate, and combine it with Winslow and its Standin on the Corner Park or with Walnut Canyon on the same side of town. Lines are rarely a problem except on holiday weekends.

There is a cafe and a gift shop with meteorite specimens, and the grounds are generally accessible, though the rim paths include steps and uneven ground. Bring sunglasses, water and a hat, and use the telescopes on the observation deck to pick out the distant features at the bottom of the crater, which is easier than it sounds.

Seasonal conditions shape the visit. Summer brings strong sun and occasional monsoon storms in the afternoon, while winter can bring snow, ice and wind that close the outer rim trails but leave the indoor exhibits open. Spring and fall are usually the most comfortable. If you are driving between Flagstaff and Albuquerque or the Petrified Forest, the crater is an easy stop right off the interstate, and the cafe makes a convenient lunch break.

Photographers should bring a wide-angle lens for the rim views and a zoom to pick out details on the crater floor, where old mining and research equipment can still be seen.
