Other/historical names associated with this locality:
Vredefort dome
A huge meteorite impact structure, formed about 2 billion years ago.
Original diameter estimated to be 250-300 km.
"The dome in the centre of the impact structure was originally thought to have been formed by a volcanic explosion, but in the mid-1990s, evidence revealed it was the site of a huge bolide impact, as telltale shatter cones were discovered in the bed of the nearby Vaal River." (Wikipedia)
An UNESCO World Heritage Site.
