Talk at the Hermanus Astronomy Centre – 02 October 2014

Once upon a time when the Western Cape was young …

A tale about why everything isn’t just flat everywhere.

On Thursday 02nd of October Lynnette, Snorre and I set out for Hermanus.  The first port of call was Lee’s new place in Sandbaai where Snorre was confined to his carry box, because we were uncertain what the reception from Lee’s three resident felines would be. All went very well but, just to be on the safe side, we confined Snorre to Lee’s spare bedroom when the three of us left to have supper with Pierre de Villiers, the chairman of the Hermanus Centre.

After a pleasant meal at Lemon Butta and some impromptu whale watching we headed out to the SANSA (South African National Space Agency).  They are housed in the buildings of the erstwhile Hermanus Magnetic Observatory.

Pierre introduced me and I then presented my talk. This covered the geological origins of the Western Cape and I took the audience in a time journey from the deposition of the sediments forming the Malmesbury shales in the Adamastor Ocean through to the present. Along the way we stopped of briefly to look at the formation of the Agulhas Sea, sedimentation of the material that forms the Cape Fold Belt Mountains, the folding and uplifting of those sediments and eventually the breakup of Gondwana and subsequent erosion down to its present day appearance.

After the talk we stopped off at Lee’s place for coffee and to collect Snorre.  Then we headed home to Brackenfell and packed for the weekend’s activities at the Makadas Country Festival in Touw’s River.
