Could it be ideas that are churning? Or… just rocks being worn down by time and tide? We found this little pothole at low tide. The colours and textures astounded. To think, those rounded stones and most likely many others, had worn out the softer sedimentary rock deposits. It makes you wonder just how long the process has been going on? It also reminded me of a much larger set of potholes back in South Africa… out in the direction where a certain Mr Bourke once struck it lucky!
