Arizona Meteor Crater 8 inches from real elevation data scaled down to 1/13,238 scale. This covers an area of approximately 1.66 x 1.67 miles or 2,670 x 2,690 meters or 2.7 x 2.7 km. Crater diameter is: 1.186 kilometers or 0.737 miles. This model does not have a base so it would require a square base be made to hold it. I made this to use to make a diorama but thought someone would be interested in it as well.
