There are two South Africans researching the stone circles - Adam's Calender: Johan Heine and Michael Tellinger, authors of the book “Temples of the African Gods” ( 2009).
I have moved to South Africa from Holland a year ago and traveling in Mpumalanga and the Kruger Park I noticed countless Pyramid shaped structures all over the place.
I don't think anyone has investigated the South African Pyramids so far. The reason I wrote you was that I was hoping that you would be able to shine some light on this matter (the Pyramids)
What is documented are hundreds of mostly circular stone structures spread across the Mpumalanga landscape. Near Waterval Boven there is a circular arrangement of upright dolerite stones, the monoliths form an ancient calendar named Adam's Calendar by Michael Tellinger.
The site is believed to be around a 160.000 years old, based on the rise of Orion's belt. When the Golden Mean is applied, Adam's Calender aligns with the pyramid mounds in the Barberton valley below.
Adam's pyramid are on the same 31 degrees East longitudinal line as the Great Zimbabwe ruins and the Great Pyramid of Giza.
The pyramids I have photographed are in the Kruger Park about a 150 km to the North of the Barberton Valley Pyramids and probably on the same longitudinal line.
There is evidence of ruins, pyramid shaped mountains and terraces all over Southern Africa.
