The world's biggest meteor crater - SouthAfrica.info
This country never ceases to amaze me. When someone told me about this the other day I dismissed it as a fiction or an error... there was no way it could be true without me knowing about it.
I was wrong.
Today, while playing with Google Earth, I happened to notice a clear and distinct crater ring around the town of Parys... so I Googled "Parys crater" and lo and behold... the Free State Province is indeed home to the oldest and largest clearly visible meteor impact crater in the world!
And I thought Tswaing was cool!
