Meteor Crater

Visited 2017.11.15
Near Winslow, Arizona

Created around 50,000 years ago during the Pleistocene epoch, when the area was mostly open grassland inhabited by woolly mammoths and giant terrestrial sloths, the impact crater was excavated by the arrival of a nickel-iron meteorite about 50 meters (160 feet) across.

The crater itself measures about 1,200 m (3,900 ft) in diameter, 170 m (560 ft) deep, and is surrounded by a rim that rises 45 m (148 ft) above the surrounding plains.

A piece of the meteorite resides in the Meteorite Museum at University of New Mexico, which I saw later in my trip.
