Thanks for a good read. Australia has as much airburst geo-morphology as central. Mexico. It’s a little more weathered. Bur it’s there all right. When the rest of the world starts looking seriously at the fact that very large airbursts don’t make craters. But they most certainly leave their mark. And they begin to understand the planetary scarring of large geo-ablative airburst storm events. They’ll see that the Earth has as many large, geologically recent, impact scars as any other planet in this shooting gallery of a solar system. Only a very small percentage of those scars are craters. The rest are the scars of geo-ablative airbursts. If the Aboriginal people remember more impact events than we can find craters to account for, believe them. And trust that they have good reason to fear such things.
