Red Stone Hills Framed
Here’s another Vertorama from my shoot at the Red Stone Hills on Saturday afternoon.
The Swartberg mountains near Calitzdorp are rich in an iron mineral called Hematite which oxidizes in the warm humid climate to a reddish colour, giving Red Stone Hills its name. Originally this belt of red, gravel sediments formed the Northern margin of the Oudtshoorn basin but 100 million years of erosion has left isolated koppies in a band stretching from De Rust almost to Calitzdorp. Initially eroding quite quickly, they formed an outer crust which was somewhat more resistant. However weathering has broken through some of this resulting in small caves and overhangs as well as the rather spectacular hole-in-the-wall.
