Over the 3 billion years since the impact, the land has been eroded down to expose deeper crust 25 km below the original surface. All external parts of the impact structure have been removed, but the effects of the intense impact shock wave penetrated deep into the crust - far deeper than at any other known crater - and these remain visible.Just... WOW!
When an impact crater is 3 billion years old, does that mean that it’s too old to be Bush’s fault?
