Free State Things to Do: 38 reviews and 41 photos
A meteorite larger than Table Mountain slammed into the ground at breakneck speed near what is now Vredefort in the Free State. The resulting thousand-megaton blast of energy was nature's equivalent of a nuclear catastrophe. Except that in this case, life was probably kick-started by the development of oxygen and multicellular life linked to the impact.
Excavating a crater 90km wide and 20km deep, the explosion and shock wave pulverised the earth's rocky innards, injecting shard of granite and dolomite, and forming - among other things - a huge rock-like done, known today as the Vredefort Dome. Concentric circles also cascaded outwards from the hub of the explosion, resulting in a huge mountains in an otherwise flat landscape throughout the North West Province and the Free State.
