Wednesday rocks will be my regular mid-week post of a cool, in my opinion, geo-related photo with a bit of an explanation.
Today's image is from the Cape Fold Belt (CFB), which is a mini meme started by Brian Romans of Clastic Detritus with posts by Evelyn Mervine of Georneys and Callan Bentley of Mountain Beltway.
The CFB extends for roughly 500km from Port Elizabeth to Cape Town where it takes a 90 degree turn northwards and can be followed for about 350km to Vanrhynsdorp. From the air the rocks of the CFB form very distinctive ridges which I'd always watch out for when flying to Cape Town. I get bored during flights so seeing the familiar folds and ridges of the Cape Mountains is a nice reprieve from the monotony of the Karoo. There is a cool Landsat image of the CFB here posted by Jeanine Engelbrecht.
