If you are serious about understanding impact science, you need to get this book. I bought it for $35 back when it was still available from the publisher. Now you have to pay big bucks for a copy on Amazon. Amazon.com: Coon Mountain Controversies: Meteor Crater and the Development of Impact Theory: 9780816509683: Hoyt, William Graves: Books
Other books. 30 Oct. 2025.
Now here is a picture from Dean Smith author of the above book The Meteor Crater Story. That crossing grid pattern is called Type 1 Impact Bricking. 30 Oct. 2025. You can learn more about that at: 4R: Shock Lines, Impact Bricking, Dots | mysite
Meteor Crater History
One can easily lose their perspective on size at Meteor Crater. Especially after a few visits. Once you have been on the floor and around the rim many times it gets a little smaller in your mind, at least mine. So I have a few images that I keep near me to remember how really big things are there. This is one of the boulders that has rolled down from the rim over thousands of years. We see them as small objects resting on the crater floor. As the second picture shows Paul Harris my friend and I are standing in front of that boulder which is about 15 feet high and just as wide and deep.

Barringer is not alone in going broke in a great scientific engineering endeavor. Both Edison & Tesla did the same, Edison in iron mining like Barringer.

an English astronomer, proposed that the craters on the Moon result from the collision of solid objects. This proposal was made in the 1870s, and it marked the beginning of the modern understanding of lunar craters as impact craters. Proctor's work laid the groundwork for the scientific community to recognize the impact origin of lunar craters, which had been previously thought to be volcanic in origin. His proposal was not widely accepted at the time, but it was a significant step towards the development of lunar geology and the understanding of the impact processes that have shaped our solar system.
The Bogus Earth Impact Crater Exclusion Theory
-
Mercurian: 414 craters (7.9%) 38 % Earth Size
-
Lunar: 1,624 craters (31.1%) 27% Earth Size
-
Martian: 1,092 craters (20.9%) 50 % Earth Size
-
Venusian: 900 craters (17.2%) 95% Earth Size
-
Others: 1,198 craters (22.9%)
Distribution of named craters in the Solar System as of 2017[2][3][4][5][a]
Statistically you can see Earth should have about a thousand named craters by now, yet is only 200, embarrassing.
Raft/Plate Tectonic Crater Removal Theory.
First of all any theory that is not general i.e. special case is suspect. What preports to be new crust is impact tectonics.
Somehow Earth got missed theory.

A brief systems analysis of why some craters are recognized and others not. Planetary Science crater analysis was developed by Gene Shoemaker in the 1960's using atomic craters and small impact craters. The criteria he developed is very limited and such a flash card type system is incongruent with the first law of impact research "All craters are unique." The approval body for craters has little funding and is located in Canada which has more approved than other countries which is another system bias. While atomic craters do make a shock waves they are fundamentally different from a kinetic explosion. 5 Nov. 2025.
Impact-formed complex diamond-graphite nanostructures
Impact diamonds from Canyon Diablo iron meteorite (ASU meteorite collection). Red arrow points to the locality of the diamond grains inside kamacite (α Fe/Ni alloy).
Shock waves resulting from asteroidal and laboratory impacts convert sp ² -bonded graphitic material to sp ³ -bonded diamond. Depending on the shock pressure and temperature conditions, complex nanostructures can form that are neither graphite nor diamond but belong to the diaphite material group, which are characterized by structurally intergrown...
