Meteor Crater, also known as 'Barringer Crater' is the best preserved impact crater in the world. Created by the impact of an iron meteorite 50,000 years ago, this 1.2 km diameter feature has been preserved by the dry desert of Northern Arizona. Between 1903-1929, the site was commercially explored in an effort to recover valuable native iron of the Canyon Diablo meteorite that was believed to be buried beneath the crater structure. Ultimately, these operations were discontinued as no commercially significant quantities of iron were discovered. Remnants of those mining activities can be seen in abandoned drilling apparatus in the center of the crater floor and the mining houses and access road just outside of the south rim.
Although commercial mining has long since ceased, the crater continues to be used for scientific exploration. During the Apollo era, the site was used as a training ground to prepare astronauts to navigate craters on the Moon. More recently, geologists have studied the shape and structure of the crater. The massive offset blocks of sandstone and limestone, due to impact into pre-existing faults, can clearly be seen in the northwest and southeast 'corners' of the model. In addition, the blocks of rock forming the crater wall are tilted outward and away from the center, as a result of the tremendous release of energy that folded the rock back onto itself. Even the large boulders that were ejected from deep inside the crater are seen clearly just outside the east and west rims. The details contained in this model allow anyone to become a virtual field geologist and experience the results of the awesome destructive power that has shaped the surface of the Earth, Moon, and every solid body in the solar system.

This is TinyMtn's first direct use of LiDAR data, and the results are stunning. Even at the full 20'' size, this model still won't show all the details that are in the raw data. There are bumps for every tree and shrub, every rock and car, and even a fence. We will continue our pursuit to create the most detailed and accurate models of real places on Earth.
Model scale is 1:8200
Model covers an area approximately 1.6 by 1.6 km
Altitudes covered: 1556m to 1750m
There is no vertical exaggeration applied to this model. This is a true-to-life scale model of a real place.

TinyMtn models are most affordable in the "White Strong and Flexible" and "Sandstone" materials. This model is in "White Strong and Flexible." When you receive the model, there may still be Nylon dust on it from the printing process. Use either an airbrush, canned dust blower, or a soft old toothbrush to remove this dust. Do not get the "White Strong and Flexible" material wet, and don't prime it or use any oil-based paints on it. You can safely seal it with Polycrylic or a similar water-based clear spray sealant.

The "Frosted Detail" material will show more detail, but is semi-transparent and has an uneven surface texture when unpainted (due to the orientation of the model when Shapeways prints it). It may show up feeling a little greasy and with small crystals in crevasses. Clean those off by soaking the model in warm (but not hot) soapy water and brushing with an old toothbrush. To get the surface to an even matte finish, spray with a few light coats of sandable primer (white automotive primer works), and then do a baking soda grit-blast.
These models have been optimized for the above materials, and are not offered in other materials for strength or cost reasons. If you need one in another material, please firstname.lastname@example.org
