希克蘇魯伯隕石坑
The original crater is estimated to have had a diameter of roughly , but that has been eroded. It would have been larger than the Sudbury Basin and the Chicxulub crater. The remaining structure, the "Vredefort Dome", consists of a partial ring of hills in diameter, and is the remains of a dome created by the rebound of rock below the impact site after the collision.
