Pilanesberg National Park is a wildlife reserve in South Africa, a couple of hours northwest of Pretoria. It's kind of cool because it's like somebody dropped this circle of hills in the middle of an otherwise featureless plain. You might think it is the site of an old meteor impact, but the rockhounds tell us it's the remains of a billion year old volcano. The
Ngorongoro Conservation Area in Tanzania is another old volcano that has become a wildlife preserve. Daring daughter was there a few years ago. I mentioned this at lunch the other day and Jack mentions the
Richat Structure, which is neither an old volcano nor an impact crater. Then I recall something about
a big crater in the Congo. Did I post something about it? I did.

Africa Craters
Impact Craters in Blue. Other structures in Burnt Ochre. |
All this prompted me to plot all these various features on a map of Africa.
Update March 2019 embellished map caption and added link.
