Vredefort Crater, Largest and Oldest Known Impact Crater

NASA image Vredefort Crater

One of the largest and oldest known impact site on earth is located in what is now South Africa, and due to the extreme deformation conditions, dramatic evidence of the “rebound dome” is still clearly visible by satellite. The rock exposed now was turned on its edge and uplifted by the rebound, originally very deep granite below the surface, and is now the site of much gold mining.
