Meteor Crater is a meteorite impact crater about 37 mi east of Flagstaff and 18 mi west of Winslow in the northern Arizona desert of the United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Cañon Diablo. Because the United States Board on Geographic Names recognizes names of natural features derived from the nearest post office, the feature acquired the name of "Meteor Crater" from the nearby post office named Meteor.
Meteor Crater lies at an elevation of 5,640 ft above sea level. It is about 3,900 ft in diameter, some 560 ft deep, and is surrounded by a rim that rises 148 ft above the surrounding plains. The center of the crater is filled with 690–790 ft of rubble lying above crater bedrock. One of the interesting features of the crater is its squared-off outline, believed to be caused by existing regional jointing in the strata at the impact site.
