The Island Archway, standing between two cliffy headlands of Loch Ard Gorge like the arc de triumph of the Roman emperors. The Gorge's geological variety provides clues as to how The Twelve Apostles had been formed: first, the softer parts of the shoreline would succumb to erosion, leaving the harder sections in between to become headlands. In the next phase, headlands themselves would start being worked on by the elements. Waves would attack their sidewalls, giving birth to isolated baby-blowholes that would keep enlarging to the point where two opposite blowholes would join together, tunnelling through the headland to form an arch or a bridge (photo).
Fast-forward a few thousand years and the arch would become too fragile, its middle section collapsing under its own weight to create two stacks. In the final stages of the process, each individual stack would be ‘undercut’ by rushing waters, which would erode the base just above the sea level and eventually cause the stack to crash into the ocean.
Very amazing photo. Who here it living, lucky man.
Very interesting description! I put in Best of!
Sad news, the arch collapsed last week. It is now two stacks only!
I was priveleged to walk accross London Bridge arches nearby in 1970 and have photos of that, but alas one of it's arches collapsed in 1990, so it is now an island arch.
I believe one of the Twelve Apostles has also collapsed.
Such is the processes of geology and nature.
Hi Philip, sad to hear that. The stack was a masterpiece of geology. Martin
