Ogof Golchfa / Porth Clais -- one of the most precious Quaternary sites in Wales

 

 

This is a wonderful photo published on Facebook by Guy Candler.  It shows the cave called Ogof Golchfa and the rocky peninsula on which I spent many many hours back in the day, measuring and recording the stones and the sediments.  Note the rough rock platform on which the raised beach and other sediments rest.  If you click to enlarge the photo you can see the broad dolerite dyke bounded on both flanks by thin sandstone beds that are now vertical (the dyke might actually have been a sill, if it was emplaced contemporaneously......). The raised beach exposures around the cave were -- and still are -- almost impossible to get at.
