Spheroidal weathering in Kruger National Park, South Africa. This outcrop is Archean granite of the Kaapvaal Craton. It’s producing a nice little inselberg in the low veld; good klipspringer habitat.
“Kopje” is the word I learned to call these things in East Africa, but I guess the proper Afrikaans spelling is “koppie.”

What is the surface composed of on which the inselberg is resting? Is it the same granite?
Yep – same stuff. Tip of the iceberg, as it were.
