Meteor Crater Flagstaff

Meteor Crater 14km from Interstate 40 

When driving 60km east from Flagstaff on the Interstate 40 you have the chance to visit a real meteor impact crater. It's the famous and well preserved Meteor Crater (other common names are Canyon Diablo Crater and Barrington Crater).

At the bottom of the crater previous mining activities are still visible aswell as a astronaut plaque

The crater is the result of an impact 50.000 years ago by an object (asteroid) of 50m, a weight of 300.000 tons and a speed of 12km/s.  The result is enormous : a crater 1,2 km in diameter and a depth of 170m. The rim around the crater is 45m above the ground level.

Holsinger Meteorite - 639kg - Visitor Center Meteor Crater

The biggest piece found of this Ni-Fe meteor is a meteorite called the Holsinger meteorite and has a weight of 639kg and can be seen in the Visitor Center of Meteor Crater.  Last year I visited Adler Planetarium in Chicago which shows a smaller fragment of 460kg of the same meteorite.
