On Saturday the 10 November, the Bingie Residents Association’s geologists Geoff Scott and Philip Hughes took us on a geological time walk starting at Congo Headland, along the Bingie Dreaming Track and finishing at Meringo Beach. Twenty-five people including many non-members and 2 young children walked the geological time span from the 29 million year old Coila Basalt at Congo Headland and then along the Bingie Dreaming Track to 115,000 year old interglacial ‘fossil’ cliffs of the Meringo Creek Formation. This was a time when the temperature was 2 degrees warmer and the sea level 5 metres higher. We finished back in time again with Coila Basalt fractured into large 4-8 sided columns and strewn at the northern end of Meringo Beach. It was great day of learning about how our shores and soils were formed so long ago. For more geology details download the document congo-meringo_notes from the link below.
