Tension Cracks

Posted by Gerhardus Geldenhuis on 19 December 2012 in English (English)

Saw a really interesting set of "cracks" looks like tension cracks in a anticline or maybe an underlying dome. Having not seen the Geology first hand it would be difficult to judge but worthy noting down for later inspection.

The Vaal river has filled in these cracks and it does not look man made. Most of these inflows have a stream connected to them and there is no man made structures or other indicators that would point to a more human origin.

Location: Nala Ward 10, Nala Local Municipality, Lejweleputswa District Municipality, Free State, RSA
